A solid foundation for a cloud architecture is essential to the success of any application. An overarching vision for the application provides direction, but there are numerous decisions required in developing its architecture. Inevitably, a lack of planning or structure causes significant pain and headaches down the road. For example, more than half of companies report difficulty with their DevOps journey. In fact, long-term planning is considered a new practice for most with only 34% of firms reporting that they plan for long-term IT architecture. From cloud assessment services to assessing the level of expertise on your team, a solid cloud architecture foundation starts with answering key questions rather than every single question.
Considerations for Cloud Assessment services
Evaluating all the decisions for a cloud architecture is overwhelming. Here are a few considerations to help establish a sturdy foundation that will benefit you:
Cloud dependent or cloud agnostic?
The pivotal first decision is whether the application will embrace cloud-native hosting, or if it is better suited for a cloud-agnostic platform. My choice – go with cloud-native and reap the benefits of speed and simplicity. Cloud-native offers benefits such as autoscaling, a pay-per-use model, and faster development.
Which Database?
SQL or NoSQL? Graph? Distributed? Will it be self-managed or cloud-hosted?
Data is your most valuable asset. Selecting the right database is one of the most important decisions to consider. Why? Switching to another one is difficult and expensive due to the effort, complexity and outbound data charges. For instance, cloud providers don’t charge you to put data in (ingress), but they do charge you to take data out (egress).
Which application delivery/runtime?
Containers or Serverless. If you select containers, which container engine? What will you use for container orchestration? Who will manage it?
My choice – utilize a “Serverless First” approach. Most workloads are candidates for a serverless implementation. Learn more about how you can determine if your application is suited for a serverless from our guide.
What framework will you follow?
AWS or Azure Well-Architected Framework, or something else? How will you ensure security from end to end of the entire stack?
What logging and visualization tools will you use?
The default logging and visualization capabilities provided by the cloud providers are basic with limited capability. Given that “logs are gold,” these tools are instrumental in problem detection and diagnosis.
What will you use for CI/CD?
How will you be able to deploy multiple times per day without any service interruption? Will you use one of the cloud provider solutions, or do you prefer a more cloud-agnostic approach?
4 Questions to Get Started With Cloud Assessment Services
All of these decisions could differ for each application. Taking a step back and answering key questions at a higher level will guide decisions for more detailed, technical ones. When I’m engaging with a client on an application modernization project, I start with these four questions:
- What is your cloud strategy?
- What is your container strategy?
- What is your open source strategy?
- What is the level of expertise of your team?
- Do you need cloud assessment services?
Having certainty to any of these questions yields a cohesive technology strategy for the organization. Without a set foundation for the cloud architecture, teams within an organization will act independently and operate under splintering understandings of the vision, creating havoc and decreasing speed and reusability.
Here’s a simple but sample strategy statement that would cover these questions:
Our cloud strategy is to build cloud-native applications in AWS – portability to other cloud environments is not a requirement. We prefer to use SaaS offerings and not install or implement anything that we must manage ourselves. If there is no such offering in AWS, we will utilize an open-source solution after completing due diligence and choosing the best option. Our apps follow the Twelve-Factor methodology and AWS Well-Architected frameworks to ensure availability, scalability and security.
Although it’s not extensive, this sample statement does answer the critical questions that provide a strong direction to your engineering teams and your cloud assessment services partner. The key is to develop one that’s perfect for your needs.
In Conclusion
Building a strategic cloud architecture plan starts by asking essential questions about your strategy. A game plan for cloud deployment, containers, open-source, and an assessment of team talent will provide a launchpad for successful application development.
