2 IT Must Evolve to Stay Ahead of Demands

3 Containers package applications with dependencies and isolate the runtime Easy to deploy and portable across host systems Created from immutable, layered images Isolated from a host operating system. In RHEL, this is done through: Control Groups (cgroups) kernel namespaces SELinux, svirt, iptables Docker CONTAINER CONTAINER APP APP LIBS LIBS HOST OS SERVER

5 WHAT IS KUBERNETES? 5 Orchestration of large amounts of running containers spread across a lot of hosts. Kubernetes is an open-source platform for automating deployment, scaling, and operations of application containers across clusters of hosts, providing container-centric infrastructure.

14 Microservices and Container Technology

15 IT Must Evolve to Stay Ahead of Demands

16 SOA Evolution to MicroServices Source: PWC

17 A formal definition of microservices In short, the microservice architectural style is an approach to developing a single application as a suite of small services, each running in its own process and communicating with lightweight mechanisms, often an HTTP resource API. These services are built around business capabilities and independently deployable by fully automated deployment machinery. There is a bare minimum of centralized management of these services, which may be written in different programming languages and use different data storage technologies. - Martin Fowler, ToughtWorks -

18 Microservices not only about application architecture and design, it is also about organizational structure. Any organization that designs a system (defined broadly) will produce a design whose structure is a copy of the organization s communication structure - Melvyn Conway, 1967

19 Traditional organizational structures lead to siloed application architectures Source: Fowler

20 Innovative Microservices call for cross-functional teams Source: Fowler

22 Use easily replaceable units of infrastructure to efficiently manage a fleet of Microservices operated in containers Source: Fowler Pets [* : R. Bias / B. Baker vs. Cattle *

23 You must be this tall to implement Microservices

to provision a new VM?) Dev vs Ops (who is on the pager for production app outage?

24 You Must Be This Tall Self-Service, on-demand, elastic infrastructure as code (how many days/weeks to provision a new VM?) Dev vs Ops (who is on the pager for production app outage?) Automation (phoenix vs snowflake?) CI & CD Deployment Pipeline Cross Cutting Concerns

25 Traditional, Monolithic App: +: Well known technology +: easy to buy skills +: well known DB -: long deployment cycles -: long business change cycles -: hard to exchange parts Full blown microservices App : (with CQRS Pattern): +: extreme loose coupling +: easy to change / replace parts +: fast deployment cycles +: fast business changes -: added complexity -: hard to buy skills / experience -: new technologies like EventLog DB Notes: - Both can run in containers - Compromise from both worlds is possible Images: Kim Eik
