The Software Defined Enterprise

▪  Every business is an IT business ▪  Customers demand that you deliver new features faster

whilst maintaining high levels of quality ▪  Throughput and stability increases through: −  Automation −  Smaller batch sizes −  Shortened cycle times −  Reaction to feedback

Microservices

The newest old architecture pattern

11

What are MSVCs?

A collection of single purpose, loosely-coupled services, each running in its own process, and communicating via lightweight mechanisms

12

Key Features of Microservices

▪ Domain-Driven Design ▪ Singular responsibility ▪ A well published interface/API ▪  Independent Deploy, Update, Replace Scale

(DURS) ▪ Lightweight Communications

13

Key Benefits of Microservices

▪ Heterogeneity and Polyglotism ▪ Ease of maintenance ▪ Ease of upgrade ▪ Scaling ▪ Fault isolation ▪  Improved communication across teams

14

Impact to Operations

▪  Monitoring – Service monitoring and metrics improves in production

▪  Better resiliency with scaling and replication. ▪  GOOD DESIGN IS EXTREMELY IMPORTANT

Docker

No stock photography of a container ship, please.

16

What is Docker?

An open-source project that allows you to package an application with all of its dependencies into a container

17

Key Features of Docker

▪ Lightweight (compared to VMs) ▪ Easily duplicated and expanded ▪ Fast ▪ Can run on public clouds like AWS ▪ Easy to share

18

Just Another VM?

OS-level process isolation VS isolation at the hardware abstraction layer

Benefits in Continuous Delivery

▪  Portability ▪  Supported by all major cloud computing providers ▪  Standardized environment −  Consistency across release cycles −  Work with version control

▪  Isolation −  Containers isolated from each other −  Assigned resources (CPU, Memory, disk space)

▪  Clean app removal/uninstall

Why They’re a Natural Combination

Independence 1:1 Abstraction

The Enterprise Perspective

Not just for startups

Not Entirely New

EnterprisesareComplex

▪  Enterprises are complex (compared to single app portfolio companies, e.g. SaaS vendor)

▪  Cloud software makers typically have a single SaaS app, a single app stack, a single workload they need to scale on a homogeneous infrastructure. They are singly focused and resourced on delivering this one application.

▪  Enterprises have heterogeneous tech stacks, deployed globally, with on-prem or hybrid more often than pure cloud

25

Release Orchestration

▪  Can be more challenging ▪  Always confusing due to nature of the Enterprise. −  Large, disparate, geographically dispersed teams −  Multi-tiered application infrastructure. −  Functional Silos making it even more difficult to communicate

▪  Less transparency

26

Versioning

▪  Versioning of services is important - forward and backward compatibility

▪  API versioning ▪  Service versioning ▪  Dependency…but not as much

27

SecurityChallenges

App Security ▪  Shift Left ▪  Automate ▪  API emphasis

Container Security ▪  Unlike in a VM, the kernel is

shared among all containers and the host in Docker. One thin layer of access control −  Denial of service −  Kernel exploits −  privilege escalation

attacks ▪  Getting better

Average DevOps Professional salary

▪  Encourage experimentation ▪  Cultivate internally

29

Start Smart

▪  Can be greenfield, but best in complex situations

▪  Start with an existing monolith −  New features as microservices −  Isolate them in containers

▪  Start with “safe” projects ▪  Standardize the approach
