5. Agenda 01 Start with why 02 State of the market 03 What’s next?
6. Why? “Move quickly, but safely” (David Aronchick) Platform portability Cost efficiency 1 2 3
7. Docker: the power of AND + + State of App development Survey: Q1 - 2016
8. ClusterHQ Survey (in progress…) 36% 38% 74% chose speed of delivery related responses
9. SPEED “In the first half of 2014 we thought the market would be driven by increased utilization, it turned out it was SPEED...” Scott Johnston, Docker
10. Components of Agility... Agility Latency Throughput Scalability Delivery Pipeline Value chain Team Structure Architecture Contention Coherence (of your organisation and processes, not just your software!) CI/CD DevOps Containers Microservices Cloud How fast can you deliver software? + How fast can you respond to runtime changes? Orchestration
11. Docker: driving force behind modern app initiatives Source: Docker, State of App development Survey: Q1 - 2016
12. Understanding portability So there’s this thing called the public cloud... FROM: “we can’t move to the cloud because…” TO: “we’re moving to the public cloud, so we need to fix these issues...”
13. The drive to the cloud “Our goal is to be [able to be] 100% on the public cloud (any cloud). It’s just obvious. But we can’t be only on one public cloud…” - Don Duet, Head of Technology, Goldman Sachs Typical enterprise target: AWS + 1 + Data centres
15. Symbiosis Containers are the portability layer that enable enterprises to move aggressively towards public cloud with confidence. “We’re attaching to massively funded cloud projects left, right, and center...” - Scott Johnston, Docker
16. How portability drives Azure Container Service strategy • Microsoft’s container efforts are open and standard ◦ Partnered with Mesosphere and Docker on Azure rather than develop own schedulers ◦ ACS is Linux-first, with Windows coming ◦ Windows support is being done by contribution to Docker OSS “This is important to customers because in the fast-changing cloud ecosystem they want open systems without lock-in…” - John Gossman, Microsoft Azure Architect
17. Foundations and (anti-) lock-in CNCF, CFF, OCI, … • Help vendors align & trust each other • Gives adopters assurance
18. CNCF Mission & Membership “The CNCF will harmonize emerging technologies and foster innovation in container packaged, dynamically scheduled, and microservices based application development and operations.”
19. Case study: Goldman Sachs Top three initiatives: 1. Velocity of Change 2. Private to Public 3. Proprietary to Open Scale of the challenge: • 8K technical employees • 5K applications • 75K database instances • 39 PB data (59% growth) • 165K servers Vast majority already on internal cloud infrastructure Source: Don Duet, GS European Tech Founders Summit May 2016
20. Case Study: Skipjaq - Docker + Kubernetes Why containers? • Hide underlying platforms (AWS, GCP, Azure, and vSphere) • Flexible deployment topologies • Local development • Decouple packaging and topology Why kubernetes? • Needed to be universal, not just AWS (e.g. ECS) • Liked the pluggability of Kubernetes (logs, volumes, network, …)
21. Case Study: Skipjaq “The initial experience of going from no containers to basic kubernetes was incredibly smooth. It took about two weeks and we had a full stack running… All-in-all it was about seven weeks to get fully-integrated with kubernetes for volume management, service handling, log shipping, monitoring.” - Rob Harrop, CTO
22. Case Study: Skipjaq “We have containers from the developer desktop right through to production. The same containers can be arranged in clusters of varying size on platforms ranging from AWS to vSphere. We've isolated all the platform-specific bits into the thin layer that is the K8S cluster. Even their K8S tooling makes cluster config easy.” - Rob Harrop, CTO
23. Case Study: Atomist “We wanted a platform suited for the cloud, focusing mostly on resiliency to failure and evolvability. We also wanted an active, preferably open platform. Kubernetes and Docker Swarm rose to the top of the list… Kubernetes appeared to be geared for large scale deployments and have better engineering around ops. Docker was more geared towards developers…” - David Dooling, Atomist
24. State of the Market • Everyone is winning! (A rising tide…) • Containers are in production • Revenue is now flowing • Typical (enterprise) customer journey is 18 - 24 months
25. Docker has over 10K customers... • 10,000 cloud customers, 75+ F500 customers Source: Docker
26. … and a thriving ecosystem Source: Docker
27. Kubernetes is on the rise Stack overflow questions (via Chris Gaun)

30. Yet Docker... vs
31. Docker Survey 2016
32. ClusterHQ Survey What container orchestration tools does your organisation use? (check all that apply)
33. Containers are in production Sept 2015, O’Reilly via Docker June 2016, ClusterHQ Survey 76%
34. Amazon ECS “A growing number of AWS customers across healthcare, hospitality, media and entertainment, and other industries have embraced Docker and committed to going into production. We built Amazon EC2 Container Service (ECS) to be the best place for these customers to run Docker in production securely and at scale.” - Deepak Singh, Amazon ECS. • ECS is a result of the traction the AWS team were already seeing • Container management, scheduling, and deep integration with AWS platform • Examples: Linden Lab, Empire
35. Amazon ECS Partner Program
36. Azure Container Service • Has only been generally available for a few weeks • Serious usage already - sustained large deployments • Usage going up every day, not dropping at weekends “The team is also getting far more inquiries that we can handle quickly, so interest is higher than anticipated” - John Gossman, Microsoft Azure Architect
37. Mesos is on the rise “Uber has recently started transitioning most of its services, including the storage services, to run on top of Mesos” - Matthias Eichstaedt “Service style applications, batch jobs, and stream processing alike, from a variety of use cases across Netflix rely on executing container based applications in multi-tenant clusters powered by Mesos and Fenzo.” - Sharma Podila, Netflix
38. Microservices are on the rise…
39. Yet Docker...
40. Docker Survey 2016
41. ClusterHQ Survey
42. Microservices are on the rise… 3.66M Spring Boot: Monthly Maven downloads Source: oss.sonatype.org, via Pivotal
43. Microservices and containers “We’ve seen the whole trend towards microservices and Docker come up together. Customers tell us that they value the scale and agility provided by the AWS platform when coupled with the developer productivity benefits of Docker’s dependency management and deployment capabilities.” - Deepak Singh, Amazon ECS
44. Cloud Foundry is on the rise... CF Summit 2016 - 2000 attendees 173 user groups, more than 33,400 individual members
46. Cloud Foundry is on the rise... Idea -> Feature: Weeks -> 2-3 days Application Scaling: Months -> minutes
47. Typical customer journey “We see about 20% top-down, and 80% bottoms-up adoption in enterprises” - Scott Johnston, Docker 1 2 3 LAND: lift-and-shift existing app (no microservices), adopt CI etc. 6-9 months PRODUCTION: getting the first app from there into production, about 6 months PLATFORM: floodgates open and big re-platforming project begins... 12-15 months
48. Typical customer journey: Kubernetes example LAND: starts with one app in one data center EXPAND 1: several apps within one data center EXPAND 2: bridge several data centers “[This customer] wants to leverage existing data centers (each of which have thousands of nodes) while increasing their cloud footprint. They will migrate everything to Kubernetes running everywhere over the next two years.” - David Aronchick, Google
49. Typical customer journey: Cloud Foundry example TOP-DOWN enterprise sale, it’s all about apps, not containers... Once the platform is in… • Repeated experience: 500+ devs, 1,000+ apps in first couple of months • V. low ops overhead: e.g. 1500 apps onboarded in 6 months, < 2 people to run
50. Investment funds continue to flow... • Weaveworks $15M Series B (May) • CoreOS $28M Series B (May) • Rancher Labs $20M Series B (May) • Pivotal $253M Series C (May) (+ $400M debt/equity swap) • Sysdig $15M Series B (April) • Docker $95M Series D (April) • Mesosphere $73.5M Series C (March)
51. What’s Next? Right now we’re seeing this change from a simple “let’s run containers!” to “we’re building apps… and of course we’re using containers.” - John Gossman, Microsoft Azure “We’re seeing a shift with many customers starting with the application, not the infrastructure.” - Deepak Singh, Amazon ECS
52. What’s Next? • A heterogeneous world • The value line moves up • Giving customers what they want (delivering on velocity and agility) ◦ Containers are the easy part!
53. Multi-cloud: by accident or by design... “Bridging multi-cloud and on-premise environments is the reality for enterprises, for many years to come.” - David Aronchick
54. Multi-cloud challenges • “Any cloud” approach needs a portability layer ◦ By definition, not tied to any one cloud vendor • An important ‘cloud’ is the developer laptop • Applications may run in several different environments as part of the development lifecycle ◦ Even if production migration is rarer • Need to consider not just compute, but also networking and storage ◦ Data gravity vs data agility
55. Multi-platform? The Platform Wars What kind of platform? Bottoms-up? DevOps, PlatformOps, AppOps, & IT Orchestration is a layer “The Platform Wars, Begun They Have” - Alexis Richardson
56. Deployment granularity Physical Virtual Container Unikernel Lambda Becoming finer-grained Enterprise may well end up with all of these! Mixed deployments, E.g. GS, NOTHS

74. Microservices challenges: thoughts from Sam Newman
75. Cognitive load Source: Adrian Cockcroft
76. Problems that remain • Security is a mess • Understanding what services depend on what other services is something everyone seems to be hand rolling • Even basic things like knowing who to talk to about a service is difficult in larger organisations • Very little is being done to help developers, outside of platforms that make things easier to deploy • Data is still problematic - replication, and moving process to data
