Quick History Lesson

We used to own the servers

+ Total control of hardware and software

+ No vendor lock in

 

- Expensive

- Required specialized knowledge

- Hard to scale

Then we moved everything to the cloud!

+ Total control of software

+ Reduced cost and barrier to entry

 

- Vendor lock in

- Required specialized knowledge

Who needs DevOps?

a.k.a Platform as a Service

+ No need for specialized knowledge

+ Reduced cost and barrier to entry

 

- Little to no control over hardware or software

- Very high level of vendor lock in

Took back control with Containers

+ Greater control and ability to decide infrastructure

+ Reduced cost and barrier to entry

 

- Specialized knowledge required

- Many moving parts / multiple points of failure

Software as a Service

+ Implement features and functionality without building your own

+ Reduced cost and barrier to entry

 

- Vendor lock in

- Additional points of failure

Function as a Service

Serverless, Cloud Functions, Microservices, Server as a Service, etc.

Serverless: someone else's servers ;)

 

Autoscale + No Idle Costs - Rob Mensching

+ Decentralized features can evolve independently

+ Reduced cost and barrier to entry

 

- Vendor lock in*

- Decentralized infrastructure can be harder to maintain

SaaS Applications

Why SaaS Applications?

 

You don't care about where it's hosted

 

Each endpoint provides singular functionality

 

You typically only get charged for usage only
