This document discusses cloud adoption frameworks and provides examples. It begins by defining cloud adoption frameworks as collections of best practices to help organizations successfully migrate to the cloud and avoid common mistakes. It then provides overviews of the Microsoft and AWS cloud adoption frameworks, describing their strategic and tactical components. The document also presents three mini case studies showing how organizations have used cloud adoption frameworks to successfully migrate applications and infrastructure to the cloud. It concludes that cloud adoption frameworks provide both a high-level strategic view and tactical guidance for a successful cloud migration.

All new deployments to the cloud. Create Cloud Centre of Excellence (CoE)*. • All-In – Data centre exit. Mass Migration. • Cloud-Native – application modernisation + cloud-native application architectures

- Where you start across the DevOps pipeline is very dependent on the organisation Where is your constraint?
- Where you start across the DevOps pipeline is very dependent on the organisation Where is your constraint?
- The reality is that the Agile bit has gotten a lot better… and the bottleneck (the constraint to delivering value) was rapidly becoming the Ops bit… Lead times for servers too slow (even in virtualised environments) Too busy fighting fires Badly designed processes Too many silos even within operations And of course the biggest bottleneck – outsourcing…

- Also – it is a move away from something that is just a commodity
- Microsoft’s is a bit of a halfway house between a CAF and a CMF…
- Teams that adopt both Cloud and DevOps together report an 81% acceleration, compared to a 52% or 53% boost for DevOps or Cloud in isolation. 2 When we merge technology and working practices in this way, the things we’re seeing are: Everything-as-code This is the foundational practice that everything stems from Operability-by-design Operability requirements, or non-functionals, become first class citizens Considered at design time, not just transition time Cloud-native services Use of technology and automation to do things better, faster and cheaper Agile and lean practices Small batch sizes Fewer queues, fewer handoffs With risk managed by repetition Aligned goals less conflict between individual incentives or team/functional incentives, and the things that really matter 2 https://www.ca.com/us/modern-software-factory/content/devops-and-cloud-better-together.html
- Click Click Click Click Click So when we looked patterns practices and cultural norms we found they broke down into 5 key areas – which leads to what’s called the CALMS model of DevOps <click>
- What they found was that high performing IT organisations were different in 5 key areas… Culture – they embraced change, were more autonomous and more empowered Automation – they were leveraging the latest automation tools like Puppet, Chef and Ansible Lean IT – they were embracing Lean IT principles borrowed from manufacturing (particularly automotive and the Toyota Production System e.g. Kanban) but more importantly focussing on small batch sizes and the flow of work through the system Measurement – they were using advanced measurement techniques to provide constant feedback on their customer needs, and the impact of their IT initiatives. Less opinion, more data science! Sharing – a focus on breaking down silos between departments and sharing knowledge and best practice, often using ideas drawn from open source software development. Let’s quickly drill down into 2 of those in a bit more detail – breaking down the silos and the flow of work… [click]
- Where you start across the DevOps pipeline is very dependent on the organisation Where is your constraint?
- The idea of a DevOps product delivery team is that they own a defined product from initial design and development right through into production deployment AND operations – Dev & Ops together in a vertically integrated team. The product owner is empowered to prioritise the backlog of work, based on the organisational goals, customer needs and the fast feedback of data from customers and product (remember the M for measurement in CALMS). The goal here is to balance out the “user stories” (new features) with the “Operability stories” (things that make it easier to manage, reduce outages or cloud hosting costs etc). All of this underpinned by a focus on automating as much as possible, to free up time for higher value work.

- Changing behaviour is hard but behavioural change moves in a fairly predictable way.
- What we often see is what we call the Icecream sandwich model of organisational change C suite want it because they don’t want to end up like Paul Pester… Engineering want it because they want to learn all those shiny new skills (cos we like shiny!) Middle Management… are terrified of letting go of command & control because they don’t know how to LEAD so they are frozen in fear…
