2. • A µServices based architecture takes a monolithic problem and break it down to be delivered as a set
of independently, individually developed, run and operated services
• Instead of building a single, monolithic application, the idea is to split your application into set of
smaller, interconnected services
• Each µService might have its own architecture, implementation language, configuration, release
cycle
• Each µService might expose a set of APIs to other services or clients.
Same Function
But broken down to a
collection of collaborating
services
Microservices

3. • The Benefits of µServices are very apparent at large scale development and delivery
• It tackles the problem of complexity
• each service can be constrained to scope of one business value
• easier to develop and maintain
• Enables each service to be developed independently
• separate teams for each service, different technology stack
• enables each µServices to be deployed independently
• one team (UI for example) can iterate features more rapidly
• Each service to be scaled independently
• number of nodes per service
• hardware used for each node
• µServices makes DevOps possible
• It is much easier to DevOps a set of µServices compared to a single monolithic app that needs to
be updated all at once
Microservices

4. Like any other approach, the µServices architecture has its drawbacks and costs.
• While small µServices are preferable, too many µServices might lead to unacceptable performance and lots
of operational overhead
• The goal of µServices is to sufficiently decompose the application in order to facilitate agile application
development and deployment
• Very small services == communication, maintenance, and operational overhead
• Complexity arises from the fact that a µServices application is a distributed system
• Tolerance for partial failure. Much more complex than intra-process method invocation in monolithic
design
• Harder to test and operate
• Very little help in terms of tools and IDEs
• Implementing changes that span multiple services
• Although its not recommended, but this might happen
(happens too often? you’re composing µServices wrong!)
• Deploying a µServices-based application might be more complex
• Need to deploy a number of moving parts
Drawbacks of Microservices

5. • A µServices based architecture takes a monolithic problem and breaks it down to be delivered as a set of
independently, individually developed, run and operated services
• The benefits of µServices are very apparent at large scale development and delivery
• Like any other approach, the µServices architecture has its drawbacks and costs
• Containers to the rescue!

6. A standard way to package an application and
all its dependencies so that it can be moved
between environments and run without changes.
Containers work by isolating the differences
between applications inside the container so that
everything outside the container can be
standardized.
Containers

7. • Docker is a (traditionally) Linux Container environment that includes specifications, APIs, tools, daemons, image
libraries, etc.
• Docker regulates how users:
• Build images
• Share images with others
• Run images inside Linux Containers
• Linux Containers are
• An operating system–level virtualization method for running multiple isolated Linux systems (containers) on a
single host with high levels of isolation
• A large number of Linux specific technologies are required to make Linux Containers happen
• Namespaces (mnt, pid, net, ipc, uts/hostname, user ids)
• Cgroups (cpu, memory, disk, i/o - resource management)
• AppArmor, SELinux (security/access control)
• seccomp (computation isolation)
• chroot (file system isolation)
• The greatness in Docker is not the “invention” of containers (they were out there already) but making containers
available to the greater community that do not want to understand the above set of technologies
What is Docker?

8. Key Docker containers concepts

9. Everyone’s container journey starts with one container….

10. At first the growth is easy to handle….

11. But soon it is overwhelming… chaos reins

12. Regain control with Containers and Kubernetes

13. Kubernetes is an open-source
system for automating
deployment, scaling, and
management of containerized
applications.
It groups containers that make up an
application into logical units for easy
management and discovery. Kubernetes
builds upon 15 years of experience of
running production workloads at Google,
combined with best-of-breed ideas and
practices from the community.
