Visa Inc. Gains Speed and Operational Efficiency with Docker Enterprise Edition

#DockerCon 2017 was an opportunity to hear from customers across multiple industries and segments on how they are leveraging #Docker technology to accelerate their business. In the keynote on Day 2 and also a breakout session that afternoon, Visa shared how Docker Enterprise Edition is empowering them on their mission is to make global economies safer by digitizing currency and making electronic payments available to everyone, everywhere.
 
Visa is the world’s largest retail electronic payment network that handles 130 billion transactions a year, processing $5.8 trillion annually. Swamy Kocherlakota, Global Head of Infrastructure and Operations, shared that Visa got here by expanding their global footprint which has put pressure on his organization which has remained mostly flat in headcount during that time. Since going into production with their Docker Containers-as-a-Service architecture 6 months ago, Mr. Kocherlakota has seen a 10x increase in scalability, ensuring that his organization will be able to support their overall mission and growth objectives well into the future.
Global Growth Fuels Need for A New Operating Model
In aligning his organization to the company mission, Swamy decided to focus on two primary metrics: Speed and Efficiency.

Speed is tied to developer on boarding and developer productivity. Visa wants new developers to be able to deploy code on their first day. That means giving them tools they are familiar with and getting out of their way. It also means providing developers access to infrastructure whenever and wherever they need it.

Efficiency is tied to Visa’s ability to maximize utilization of their existing datacenter footprint while also reducing the time the team spends on patching and refreshing hardware. Optimizing their efficiency also frees up both headcount and datacenter resources to support their global growth initiatives.

While considering how they could support these objectives, Visa also has to meet the high bar on security and availability that underpins everything they do. Some of the core systems at Visa have had zero downtime over a span of 20 years!
Modernizing with Docker Enterprise Edition
After investigating different technologies and vendors who could help them achieve both speed and efficiency objectives, Visa chose Docker Enterprise Edition (Docker EE) to help them move towards a microservices application model while also modernizing their data center operations.
Visa was looking for an enterprise-ready solution and appreciated the integrated approach of the Docker EE stack which includes scheduling, service registry, service discovery, container networking, and a centralized management control plane. Docker EE allows them to manage multiple development, QA, and staging environments, gain visibility across their container environment, and retain full control over role-based access.
Visa chose two key applications to begin their Docker journey – a core transaction processing application and a risk decision system. These were legacy monolithic applications which they began to containerize into services. Those two applications are now running in production on Docker EE across multiple regions and handling 100,000 transactions per day. They consist of 100 separate containers and have the ability to instantly scale to 800 when transactions peak.
To learn more about Visa’s application architecture, watch the breakout Docker Networking in Production at Visa below:

Results and Benefits

With Docker EE now in production, Visa is seeing improvements in a number of ways:

Provisioning time: Visa can now provision in seconds rather than days even while more application teams join the effort. They can also deliver just-in-time infrastructure across multiple datacenters around the world with a standardized format that works across their diverse set of applications.
Patching & maintenance: With Docker, Visa can simply redeploy an application with a new image. This also allows Visa to respond quickly to new threats as they can deploy patches across their entire environment at one time.
Tech Refresh: Once applications are containerized with Docker, developers do not have to worry about the underlying infrastructure; the infrastructure is invisible.
Multi-tenancy: Docker containers provides both space and time division multiplexing by allowing Visa to provision and deprovision microservices quickly as needed. This allows them to strategically place new services into the available infrastructure which has allowed the team to support 10x the scale they could previously.

To hear more about how Visa was able to gain 10x scalability for their application with Docker, watch Swamy’s presentation from the Day 2 general session below:

Docker Enterprise Edition (EE) is designed for enterprise development and IT teams who build, ship and run business critical applications in production at scale. Docker EE is integrated, certified and supported to provide enterprises like Visa with the most secure container platform in the industry to modernize all applications.

The Agility and Flexibility of Docker including Oracle Database and Development Tools

A company’s important applications often are subjected to random and capricious changes due to forces well beyond the control of IT or management.  Events like a corporate merger or even a top programmer on an extended vacation can have an adverse impact on the performance and reliability of critical company infrastructure.
During the second day keynote at DockerCon 2017 in Austin TX, Lily Guo and Vivek Saraswat showed a simulation of how to use #Docker Enterprise Edition and its application transformation tools to respond to random events that threaten to undermine the stability of their company critical service.
The demo begins as two developers are returning to work after an extended vacation.  They discover that, during their absence, their CEO has unexpectedly hired an outside contract programmer to rapidly code and introduce an entire application service that they know nothing about.  As they try to build the new service, however, Docker Security Scan detects that a deprecated library has been incorporated by the contractor.  This library is found to have a security vulnerability which violates the company’s best practice standards.  As part of Docker Enterprise Edition Advanced, Docker Security Scan automatically keeps track of code contributions and acts as a gatekeeper to flag issues and protect company standards.   In this case, they are able to find a newer version of the library and build the service successfully.
The next step is to deploy the service.   Docker Compose is the way to describe the application dependencies and secrets access.   It is tempting to simply insert the passwords into the Compose file using plain text. However, the best choice is to let Docker Secrets manage sensitive application configuration data and take advantage of Docker EE with its  ability to manage and enforce RBAC (Role Based Access Control).
It is interesting that the service consists of a Microsoft SQL Server database container that is interacting with other containers that are running Linux.  Docker Enterprise Edition features this ability to run a cluster of microservices in a hybrid Windows and Linux environment.  “It just works.”
All of the problems from the beginning of the demo now seem to be resolved, but the CEO rushes in to announce that they have just purchased a company that uses a traditional on premise application. The merger press announcement will be tomorrow and there is concern about the scope and cost of updating and moving the application to a modern infrastructure. However, they know that can use the Docker transformation tool, image2docker, to do the hard work of taking the traditional application and moving it to a modern Docker Enterprise Edition containers which can be deployed on any infrastructure, including Cloud.
One final step step is needed to complete the move from the traditional architecture.   As the traditional application relies on the popular and powerful Oracle Database, it will need to be acquired and adapted.  Time to go out to the Docker Store.    Lily finds the Oracle DB on Docker Store and integrates it directly into the transformed application – and “it just works”
 The Docker Store is the place where developers can find trusted and scanned commercial content with collaborative support from Docker and the application container image provider.   Oracle today announced that its flagship databases and developer tools will be immediately available as Docker containers through the Docker Store marketplace.  The first set of certified images include: Oracle Database, Oracle MySQL, Oracle WebLogic Server, Oracle Coherence, Oracle Instant Client, and Oracle Java 8 SE (Server JRE).   
The demo ends and it’s been shown how developers can use Docker Enterprise Edition to quickly resolve a library incompatibility issues and how easy it is to take traditional applications and accomplish the first steps towards adapting them to a modern container infrastructure.

Enterprise Ready Software from Docker Store

#Docker Store is the place to discover and procure trusted, enterprise-ready containerized software – free, open source and commercial.
Docker Store is the evolution of the Docker Hub, which is the world’s largest container registry, catering to millions of users. As of March 1, 2017, we crossed 11 billion pulls from the public registry!  Docker Store leverages the public registry’s massive user base and ensures our customers &8211; developers, operators and enterprise Docker users get what they ask for. The Official Images program was developed to create a set of curated and trusted content that developers could use as a foundation for building containerized software. From the lessons learned and best practices, Docker recently launched a certification program that  enables ISVs, around the world to take advantage of Store in offering great software, packaged to operate optimally on the Docker platform.

The Docker Store is designed to bring Docker users and ecosystem partners together with

Certified #Containers with ISV apps that have been validated against Docker Enterprise Edition, and comes with cooperative support from Docker and the ISV
Enhanced search and discovery capabilities of containers, including filtering support for platforms, categories and OS.
Self service publisher workflow and interface to facilitate a scalable marketplace.
Support for a range of licensing models for published content

Publishers with certified content on Docker Store include:  AVI Networks, Cisco, Bleemeo, BlobCity DB, Blockbridge, CodeCov, CoScale, Datadog, Dynatrace, Gitlab, Hedvig, HPE, Hypergrid, Kaazing, Koekiebox, Microsoft, NetApp, Nexenta, Nimble, Nutanix, Polyverse Portworx, Sysdig, and Weaveworks
The simplest way to get started is to go check out Docker Store!

Using Docker Store
For developers and IT teams building Docker apps, the Docker Store is the best place to get the components they need available as containers. Containerization technology has emerged as a strong solution for developers, devops and IT &8211; and enterprises especially need assurances that software packages are trusted and “just works” when deployed. The Docker Certification program takes containers and #plugins through an end-to-end testing process and provides collaborative support for any potential issues. Read more about the certification program here!

Enhanced Discovery: Easily search for a wide range of solutions from Docker, ISV containers or plugins. Use filters and categories to search for specific characteristics
Software Trials: Where available, free trials of commercial software (including Docker) are available from the Docker Store.
Community Content: Developers can continue to browse and download from Docker Hub public repos from the Docker Store. The Docker Community is very vibrant and active, and community images will be accessible from the Docker Store.
Notifications: Alerts and updates are available to manage subscriptions of Docker Store listings including patches, fixes or new versions.

Publish Content to Docker Store
From large ISV with hundreds of products to a small start up building new tools, Docker Store provides a marketplace to package and distribute software and plugins in containers ready for use on the Docker platform. Making their tools more accessible to the community of millions of Docker users and accelerating their time to value with these partner solutions.
In addition, Publishers gain the following benefits from the Docker Store:

Access to a globally scalable container distribution service.
Path to certification for software and plugin content to differentiate the solution from ecosystem and to signal additional value to end users.
Visibility and analytics including managing subscribers and sales reports.
Flexible fulfillment and billing support with “Paid via Docker” and BYOL (Bring your own License) models. You focus on creating great software and we take care of the rest.
Reputation management via Ratings and Reviews.

Getting started as a publisher on Docker Store is as simple as 1-2-3!

Tips for becoming a publisher:

Create Great Containerized Content (you have probably already done this!)
Follow best practices

https://success.docker.com/store

https://docs.docker.com/engine/userguide/eng-image/dockerfile_best-practices/

Use an official image as your base image.

Docker Gives Back at DockerCon

#Docker is actively working to improve opportunities for women and underrepresented minorities throughout the global ecosystem and promote diversity and inclusion in the larger tech community.
For instance, at DockerCon 2016, attendees contributed to a scholarship program through the Bump Up Challenge unlocking funds towards full-tuition scholarships for three applicants to attend Hack Reactor. We selected two recipients in 2016 and are excited to announce our third recipient, Tabitha Hsia, who is already in her first week of the program.
In her own words:

“My name is Tabitha Hsia. I grew up in the East Bay. I come from an art-focused family with my sister being a professional cellist, my mother being a professional pianist, and my great grandfather being a famous Taiwanese painter. I chose Hack Reactor because of their impressive student outcomes and their weekly schedule. Already in my first week, I have learned a ton of information from lectures and their wealth of resources. I have enjoyed pair programming the most so far. While the lectures expose me to new topics, applying the topics to actual problems has deepened my understanding the most. After graduation, my long-term goal is to become a virtual reality developer. Seeing the integration of the solutions and tools into society excites me.”

DockerCon Gives Back  
Following the success of previous DockerCon initiatives promoting diversity in the tech industry, we’re proud to continue our efforts at the upcoming DockerCon 2017 in Austin.
With this year’s program called DockerCon Gives Back, we’re recognizing four organizations that are doing outstanding work locally in Austin and globally. Attendees at the show will have the chance to connect and support these great organizations by dropping their token in their box – each token represents a dollar that Docker will donate at the end of the conference.

            

Meet the DockerCon 2017 Diversity Scholarship winners
The DockerCon team is excited to announce the recipients of this year’s DockerCon Diversity Scholarship Program! The DockerCon Diversity Scholarship aims to provide support and guidance to members of the Docker Community who are traditionally underrepresented in tech through mentorship and a scholarship to attend DockerCon. Meet the recipients of this year’s scholarship here.

Webinar recap: Docker 101 for federal government

#Docker is driving a movement for IT teams across all industries to modernize their applications with container technology. Government agencies, like private sector companies face similar pressures to accelerate software development while reduce overall IT costs and adopting new technologies and practices like cloud, DevOps and more.
This webinar titled “Docker 101 for the Federal Government” features Andrew Weiss, Docker Federal Sales Engineer and breaks down the core concepts of Docker and how it applies to government IT environments and unique regulatory compliance requirements. The presentation highlights how Docker Enterprise Edition can help agencies build a secure cloud-first government.

Watch the on-demand webinar to learn how Docker is transforming the way government agencies deliver secure, reliable, and scalable services to organizations and citizens.

Here are the questions from the live session:
Q: Is Docker Datacenter available both hosted and as a cloud offering?
A: Docker Datacenter is now a part of Docker Enterprise Edition (EE) – providing integrated container management and security from development to production. Docker EE provides a unified software supply chain for all apps—commercial off the shelf, homegrown monoliths to modern microservices written for Windows or Linux environments on any server, VM or cloud. Docker EE can be deployed on-premises (bare metal or VMS) or on any cloud provider.
Q: Can you install regular Windows Server apps into Docker containers in Windows 2016?
A: YES. Docker running containers on Windows is the result of a two-year collaboration between Microsoft that involved the Windows kernel growing containerization primitives, Docker and Microsoft collaborating on porting the Docker Engine and CLI to Windows to take advantage of those new primitives and Docker adding multi-arch image support to Docker Hub.
Q: From an implementation perspective, do you recommend one container per virtual machine or multiple containers?
A: We see a mix. Depending on the use case you will get a range in density of containers per virtual or bare metal machine. In some science and research communities, we have seen a use case of a 1:1 container to machine  where developers are looking purely for portability of their existing workloads. However, typically containers are ephemeral, running on average for a few minutes so that number is always changing depending on how that service is scaled out or back.
Q: How do you phrase the argument that a Linux kernel is the same everywhere?
A: The kernel: This is the one piece of the whole that is actually called “Linux”. The kernel is the core of the system and manages the CPU, memory, and peripheral devices. The kernel is the “lowest” level of the OS.
Q: Is the AWS Quick Start of Docker EE available for Gov Cloud?
A: Docker Enterprise Edition (EE) Basic, Standard and Advanced are all available in the AWS Marketplace for easy deployment of a highly available Docker EE environment in about 20 minutes. Built in accordance with best practices from AWS and Docker, these templates include the latest Docker software in a variety of regions and directly integrated with AWS services.
Q: Will license pricing remain the same from DDC to Docker EE?
A: Docker Datacenter (DDC) is now part of Docker Enterprise Edition (EE) Standard tier. The subscription price has not changed. Customers who have previously purchased DDC are entitled to the latest version of Docker EE Standard. For more information, visit www.docker.com/pricing.

Learn Docker with our DockerCon 2017 Hands-On Labs

We’re excited to announce that #DockerCon 2017 will feature a comprehensive set of hands-on labs. We first introduced hands-on labs at DockerCon EU in 2015, and they were also part of DockerCon 2016 last year in Seattle. This year we’re offering a broader range of topics that cover the interests of both developers and operations personnel on both Windows and Linux (see below for a full list)
These hands-on labs are designed to be self-paced, and are run on the attendee’s laptop. But, don’t worry, all the infrastructure will be hosted again this year on Microsoft Azure. So, all you will need is a laptop capable of instantiating a remote session over SSH (for Linux) or RDP (for Windows).

We’ll have a nice space set up in between the ecosystem expo and breakout rooms for you to work on the labs. There will be tables and stools along with power and wireless Internet access as well as lab proctors to answer questions. But, because of the way the labs are set up, you could also stop by, sign up, and take your laptop to a quiet spot and work on your own.
As you can tell, we’re pretty stoked on the labs, and we think you will be to.
See you in Austin!
DockerCon 2017 Hands-on Labs

Title

Abstract

#Docker Orchestration

In this lab you can play around with the container orchestration features of Docker. You will deploy a Dockerized application to a single host and test the application. You will then configure Docker Swarm Mode and deploy the same application across multiple hosts. You will then see how to scale the application and move the workload across different hosts easily.

Docker Networking

In this lab you will learn about key Docker Networking concepts. You will get your hands dirty by going through examples of a few basic concepts, learn about Bridge and Overlay networking, and finally learning about the Swarm Routing Mesh.

Modernize .NET Apps – for Devs.

A developer’s guide to app migration, showing how the Docker platform lets you update a monolithic application without doing a full rebuild. You’ll start with a sample app and see how to break components out into separate units, plumbing the units together with the Docker platform and the tried-and-trusted applications available on Docker Hub.

Modernize .NET Apps &8211; for Ops.

An admin guide to migrating .NET apps to Docker images, showing how the build, ship, run workflow makes application maintenance fast and risk-free. You’ll start by migrating a sample app to Docker, and then learn how to upgrade the application, patch the Windows version the app uses, and patch the Windows version on the host &8211; all with zero downtime.

Getting Started with Docker on Windows Server 2016

Get started with Docker on Windows, and learn why the world is moving to containers. You’ll start by exploring the Windows Docker images from Microsoft, then you’ll run some simple applications, and learn how to scale apps across multiple servers running Docker in swarm mode

Building a CI / CD Pipeline in Docker Cloud

In this lab you will construct a CI / CD pipeline using Docker Cloud. You’ll connect your GitHub account to Docker Cloud, and set up triggers so that when a change is pushed to GitHub, a new version of your Docker container is built.

Discovering and Deploying Certified Content with Docker Store

In this lab you will learn how to locate certified containers and plugins on docker store. You&8217;ll then deploy both a certified Docker image, as well as a certified Docker plugin.

Deploying Applications with Docker EE (Docker DataCenter)

In this lab you will deploy an application that takes advantage of some of the latest features of Docker EE (Docker Datacenter). The tutorial will lead you through building a compose file that can deploy a full application on UCP in one click. Capabilities that you will use in this application deployment include:

Docker services
Application scaling and failure mitigation
Layer 7 load balancing
Overlay networking
Application secrets
Application health checks
RBAC-based control and visibility with teams

Vulnerability Detection and Remediation with Docker EE (Docker Datacenter)

Application vulnerabilities are a continuous threat and must be continuously managed. In this tutorial we will show you how Docker Trusted Registry (DTR) can detect known vulnerabilities through image security scanning. You will detect a vulnerability in a running app, patch the app, and then apply a rolling update to gradually deploy the update across your cluster without causing any application downtime.

Learn Docker with our DockerCon 2017 Hands-On Labs

We’re excited to announce that #DockerCon 2017 will feature a comprehensive set of hands-on labs. We first introduced hands-on labs at DockerCon EU in 2015, and they were also part of DockerCon 2016 last year in Seattle. This year we’re offering a broader range of topics that cover the interests of both developers and operations personnel on both Windows and Linux (see below for a full list)
These hands-on labs are designed to be self-paced, and are run on the attendee’s laptop. But, don’t worry, all the infrastructure will be hosted again this year on Microsoft Azure. So, all you will need is a laptop capable of instantiating a remote session over SSH (for Linux) or RDP (for Windows).

We’ll have a nice space set up in between the ecosystem expo and breakout rooms for you to work on the labs. There will be tables and stools along with power and wireless Internet access as well as lab proctors to answer questions. But, because of the way the labs are set up, you could also stop by, sign up, and take your laptop to a quiet spot and work on your own.
As you can tell, we’re pretty stoked on the labs, and we think you will be to.
See you in Austin!
DockerCon 2017 Hands-on Labs

Title

Abstract

#Docker Orchestration

In this lab you can play around with the container orchestration features of Docker. You will deploy a Dockerized application to a single host and test the application. You will then configure Docker Swarm Mode and deploy the same application across multiple hosts. You will then see how to scale the application and move the workload across different hosts easily.

Docker Networking

In this lab you will learn about key Docker Networking concepts. You will get your hands dirty by going through examples of a few basic concepts, learn about Bridge and Overlay networking, and finally learning about the Swarm Routing Mesh.

Modernize .NET Apps – for Devs.

A developer’s guide to app migration, showing how the Docker platform lets you update a monolithic application without doing a full rebuild. You’ll start with a sample app and see how to break components out into separate units, plumbing the units together with the Docker platform and the tried-and-trusted applications available on Docker Hub.

Modernize .NET Apps &8211; for Ops.

An admin guide to migrating .NET apps to Docker images, showing how the build, ship, run workflow makes application maintenance fast and risk-free. You’ll start by migrating a sample app to Docker, and then learn how to upgrade the application, patch the Windows version the app uses, and patch the Windows version on the host &8211; all with zero downtime.
