Choosing right technology stack! A vital part of creating solution architecture is the selection of technologies for each of the components. As a solution architect, when choosing a technology, you should look at it from an architecture and development perspective as well to build resilence with agile business solutions. One of the hardest things about technology selection is that for every problem there are several technology options and a lot of information available about them. Fortunately, selecting the right technology is not that tricky and you can quickly trim the options down by considering some of the key factors that we are going to see in this post.  This article is of my thought process, and it's a checklist of non-negotiable considerations for choosing a technology stack or a COTS product based on my hands-on experience in designing and executing enterprise scale applications/services, but the list is not limited to, and does not recommend any specific technology/plat...

Hello Welcome to this post!   An effective API design is vital in a Microservices architecture because all data exchange between services happens either through messages or API calls. REST style is probably the most known as it has become common among the Web API. But lately, the gRPC framework is becoming quite popular to build high performance systems. So, you might get these questions when involving in designing an API architecture. In this post , you would be able to find answers and to understand the capabilities of gRPC framework, features of Protobuf and HTTP/2 protocol and finally overview of common use cases of gRPC over REST API. so, let's keep reading further for technical insights. REST: a brief overview Before we start looking into details of the gRPC framework, let’s take a brief overview of RESTful services first. The standard REST methods built on HTTP 1.x. with well-defined status codes help in identifying cause of problems. Generated contracts, m...

Solutions Architecture Questions 1. How did you manage the app session? Did you consider Azure Redis? 2. What are the anti-patterns that do not fit for cloud computing? 3. One of your customers wants to go for a microservices approach. How do you approach building microservices? 4. How does the microservice approach differ from other architecture? 5. Need to migrate a legacy code to microservices - what are the other frameworks and other things you keep in mind going forward? 6. Creators of microservices added 15 factors application principles/guidelines that your application should be followed. What are those? 7. 8k tables managed under one db with 3 or 4 schemas is like a bad scenario - can you give a data migration strategy? What is your thought process? How do you categorize the data? How do you want to build a tech platform for different data types? 8. Have you got experience with big data?  9. What would be one solution that you have given that helped customers greatly in ter...

What is the difference between Layers and Tiers? |    Two-tier, Three-tier and N-tier Let's learn in this post with an example. We might heard couple of times but never worried about difference between Layers and Tiers, if somebody asks this question, immediately an engineer may think like this, “ I aware about Two-tier, Three-tier and N-tier also involved in implementation of Presentation Layer, Business Logic layer and Data Access Layer but what are the difference between these terms? Or Are all denotes the same only? ” Being as an application engineer you may need not worry about any architectural terms such as layer, tier etc. However, when you became a senior professional or someone involves in application architecture design and architect activities then you should be very clear on this simple basic things. Alright, let’s start understand what those terms means? and, how each term differs from other one on the application architecture front? For ease of understan...
