## The Big Picture: DevOps & The Cloud
When it comes to cloud computing and what is offered, it goes very nicely with the DevOps ethos and processes. We can think of Cloud Computing bringing the technology and services whilst DevOps as we have mentioned many times before is about the process and process improvement.

But to start with that cloud learning journey is a steep one and making sure you know and understand all elements or the best service to choose for the right price point is confusing.

What SaaS does and in particular Microsoft 365, because I mentioned Exchange is removing that administration overhead and they provide a service that delivers your exchange functionality by way of mail but also much other productivity (Office 365) and storage options (OneDrive) that overall gives a great experience to the end-user.
Other SaaS applications are widely adopted, such as Salesforce, SAP, Oracle, Google, Apple. All removing that burden of having to manage more of the stack.

I am sure there is a story with DevOps and SaaS-based applications but I am struggling to find out what they may be. I know Azure DevOps has some great integrations with Microsoft 365 that I might have a look into and report back.

We mentioned in the SaaS section that Cloud removed the responsibility or the burden of having to administer parts of a system. If SaaS we see a lot of the abstraction layers removed i.e the physical systems, network, storage, operating system, even application to some degree. When it comes to the cloud there are various levels of abstraction we can remove or keep depending on your requirements.

We have already mentioned SaaS but there are at least two more to mention regarding the public cloud.
Infrastructure as a service - You can think of this layer as a virtual machine but whereas on-premises you will be having to look after the physical layer in the cloud this is not the case, the physical is the cloud providers responsibility and you will manage and administer the Operating System, the data and the applications you wish to run.

Platform as a service - This continues to remove the responsibility of layers and this is really about you taking control of the data and the application but not having to worry about the underpinning hardware or operating system.
There are many other aaS offerings out there but these are the two fundamentals. You might see offerings around StaaS (Storage as a service) which provides you with your storage layer but without having to worry about the hardware underneath. Or you might have heard CaaS for Containers as a service which we will get onto, later on, another aaS we will look to cover over the next 7 days is FaaS (Functions as a Service) where maybe you do not need a running system up all the time and you just want a function to be executed as and when.

There are many ways in which the public cloud can provide abstraction layers of control that you wish to pass up and pay for.
