CIOReview | | 9 MAY 2023There is nothing more satisfying than seeing code in a well-structured way, following patterns and best practices. It reduces the teams' learning curve and helps the debugging process, since understanding the code/implementation is less challenging when using a well-defined standardjust microservices will surely save you some headaches in the future.At first, architecture might seem like they take quite some time, but it is time well spent. A properly defined architecture will help you put things where they belong and more importantly, everyone working with the architecture will know where to put them, instead of just developing as you go basis. Make it scalable ­ Be sure to design an architecture that will cope with the growth and the load expected by the business. It must perform ­ It's great if your design escalates, but it takes a lot out of it if it is slow, it must be quick and keep it that way when it grows. Designs commonly fail due to lagging response times and addressing that when it is live might be a nightmare, so anticipating and designing to perform plays an important part in your architecture. Non-functional testing (performance, load, concurrence, usability, reliability, etc.) should help you make sure where your solution stands in terms of performance.Don't Over DesignSimple designs are effectively more efficient and age better than over-engineered designs, which make it complex to implement that teams will struggle when building over it, probably leading them to work around it. Be sure that you test your design, all ideas no matter how good they are. Define StandardsThere is nothing more satisfying than seeing code in a well-structured way, following patterns and best practices. It reduces the teams' learning curve and helps the debugging process, since understanding the code/implementation is less challenging when using a well-defined standard.These standards must work for the architecture and development team, where they can agree and meet halfway through these standards, easing the way both teams interact. Don't neglect SecurityWhile implementing new functionality in our shiny new architecture might be exciting, security is paramount for it to be well round up. Use automated tools that will help you scan your code for vulnerability, security breaches, and code quality. SonarQube is a popular, easy-to-implement tool that will get you going. An occasional pen test carried out by a third party will keep your mind at ease, you can also use Burp suite to perform security testing. Remember to have a security expert next to you to guide you through the process. Security is not limited to code; authentication (tokens, OAuth2, JWT), authorization (2FA, OTP, OTC)and code vulnerabilities play a big part of it, alongside many more things.Don't work in silosWorking in silos might break your architecture, generating duplicated services, operations, or entire functionality. Proper service governance might help you reuse and avoid unwanted extra effort, while it would also save you from wasting resources (human, physical, and technological). Consider governance and supervision on your standards and architecture, and make sure that teams feel the need to comply with everything that is defined so they become advocates of how things should work. This approach will broaden the control to all team members instead of centralizing in one governance team that in fact will be checking that everything complies.Create a Service EconomyService economy relates to exchange value between organizations; it enables your organisation to use services from other providers, to offer more services without the need of building them yourself. There are popular services used by multiple applications such as twitter services to authenticate, Google APIs that embed maps into applications, more sophisticated services that can create bank accounts or wire transfers. This is leading to embedded finance, which is offering banking products in non-banking apps.A service architecture can be carried out with a number of technologies; microservices and APIs are becoming very popular lately due to its simplicity to integrate, develop, loosely couple, be independent and how it horizontally escalates, being a cloud-native concept, will also save you time when provisioning infrastructure while it enhances your apps, website, or platforms business capabilities.
