WSO2 Support Services provides new users an onboard process as you start your journey deploying WSO2 solutions. As part of this process, a solution readiness checklist (SRC) will help you ensure that the solution is as intended and includes WSO2’s recommendations for a production-ready deployment.
Business usecase document:
Do you have a Business usecase document you can share or a simple statement of business
intent for using WSO2 Products ?
Identifying a use case is very important when choosing the right solution.
Identifying Products/ Features/ Extensions :
Did you identify the right set of products/features/extensions by considering their respective intended use cases?
Problems could have multiple solutions. It's important to identify the optimum solution.
Design Diagrams :
The Design diagram gives a clear visual picture of the architecture at different levels of deployment. This helps to easily review the solution on many angles. Do you have following design diagrams ?
Solution Architecture Diagram : The solution in detail with product mappings (WSO2 and other products)
Deployment Architecture Diagram : The deployment architecture in detail with product deployment / clustering / deployment tooling / automation agents / geographical distribution etc.
Capacity Planning :
It's important to identify whether the system can handle the current expected load and ability to serve future demands.
Lower (Pre-Production) Environments :
Recommendation is to verify everything in the lower environment before applying it to production.
High Availability and Scalability :
Availability of the system depends on the business functionality handled through the deployment. Our recommendation is to have at least the minimum high availability to the system. However, there are times when the system should be capable of scaling when demand increases.
Deployment Zones :
Deployment zones should be considered when you have servers with different purposes. Specific factors like which components can be deployed in the DMZ, Geographical distribution of the deployment and, data centers should be considered.
Update Process :
Is there a CI-CD process and a mechanism to verify and apply product updates?
Software can contain bugs and security vulnerabilities. Many vendors follow different approaches when issuing patches or updates which normally involves downtime and requires an automated verification process. WSO2 issues updates through the Update tool and all deployments should have an update process configured to accept the update as described here.
Deployment Infrastructure and Recomendations :
It's always recommended to configure the deployment with vendor tested products and solutions. This document document contains the resource recommendations for WSO2 servers and this document contains the recommendations for DB servers.
Test Plan :
Do you have a test plan covering all the use cases?
It's recommended to have a test plan covering all the testing scopes and activities covering for all use cases.
