Serverless architecture is computing the need of the hour, and numerous companies are heading this route. You’re probably wondering whether you should make the transition too. You can reap enormous benefits from this application. However, the process may not be easy as it seems for a SaaS Company.
What should you do to make the transition? Nearshore development teams can help you move to serverless smoothly at a reasonable cost. They will help you maneuver through the challenges to accomplish the ultimate goal; going serverless and becoming more efficient.
To learn more about microservice to serverless transitioning, read on.
The Challenges When Moving From Monolithic to Microservices
The ever-changing business demands necessitate transitioning to new tools and technologies. New developments such as the DevOps are challenging in monolithic applications. Hence, most business owners are forced to move from monolithic to microservices. What are the challenges involved in this transition?

Decomposition
Microservice architecture is complex compared to monolithic applications. So, when moving from an existing monolith to a microservices architecture, you will need to use the right tools to lower the risks involved. This process involves decomposing the application into granular microservices.
Eventually, you get more moving parts in the application that can lead to infrastructural and operational overheads. For instance, deployment, security, and configuration management.
Testing
Before you get to run the application, you have to test it to avoid problems like rollbacks. Unfortunately, testing microservices can be difficult because the engineer you contract to write the test case must have a vast knowledge of each service that is part of the solution.
In addition to that, microservices are usually asynchronous, which poses many difficulties as you test. While you can adopt different approaches to solve the testing challenges, the process can be cumbersome and take much time. As a result, companies opt for nearshore software outsourcing in such situations since it’s easier to access top talent that way.
Persistence
A monolith application usually contains a single data store. On the contrary, the microservices application has multiple databases, each for a specific service. Understanding how you can manage this decentralized data is challenging.
Additionally, splitting the monolithic application to fit the microservices application is stretching. The reason being, as you break the application, you have to maintain transactional integrity and data. Moreover, you have to query data that spreads across multiple services.
Organizational Challenges
Moving from monolithic to microservice architecture poses organizational challenges, for instance, the organization’s structure. When using a monolithic application, a business will have large teams attending to different roles. For example, database administration, quality assurance, and development.
However, for microservices to be successful, good communication is necessary between the stakeholders and team members. This structure involves hand-offs that cause slower development cycles. The good thing is that nearshore staff augmentation can fix this for you.
Transaction Management
Monolith applications entail in-process invocations making transaction management easy for businesses. Conversely, a microservices-based application has each microservice maintaining a different database. Thus, you have to consider each of these, making transaction management difficult.
Moreover, the stateless nature of microservices demands several remote invocations to fulfill a request. Some businesses address this challenge through event-based programming to notify a microservice anytime a change takes place.
Inter-Process Communication
Typically, in every distributed system, all parts should communicate with each other. Microservices is no exception in this, and therefore organizations are forced to use inter-process communication. However, inter-service communication poses numerous challenges when employed in this application.
Unlike in microservices, monolithic components communicate through function calls. Thus, you don’t have to deal with service interaction issues and come up with ways to handle failures.
Deployment
Deployment of monolithic architecture involves setting one application per machine/host and then scaling the application vertically. On the other hand, deployment for a microservices-based application uses various patterns.
For instance, One Service instance per Container and Multiple service instances per Host. Consequently, you may experience operations overhead since you are running numerous services and version management.
Now, Moving From Microservices to Serverless, What Does It Mean for a Nearshore SaaS Developer?
Migrating from an existing microservices architecture to a serverless application is key to reducing the organization’s expenditure on technical resources. However, the process comes with its challenges.
While most businesses are planning to transition due to the numerous benefits of serverless architecture, they need to understand what it involves.
What does moving from microservices to serverless entail?
Comparing Microservices and Serverless Architecture
The first thing you should consider before transitioning any application is the difference between the two solutions. Understanding where the microservices architecture is strong is necessary when designing the application in a serverless context.
The reason being, the closer the source architecture is to the target, the lesser challenges you are likely to face in your migration. Thanks to the numerous elements common in microservices and serverless, they give you a less difficult experience. Nevertheless, they have differences that account for why serverless is gaining more popularity.
Microservice architecture defines a function and assigns it its private web application. For instance, a payment service processes payments while an inventory service focuses on physical goods warehouse and online drop shippers to cater to customer orders.
The serverless application breaks the microservice distinction further into the constituent actions to be taken. For example, when the microservice has a payment server with distinct endpoints such as charge or refund, a serverless will assign different functions to these endpoints.
Preparing to Migrate
Programming language concept by a system engineer.The next essential thing you need to do is taking full stock of what you want to migrate. Below are some areas you need to focus on as you prepare to transition
Mapping Date Usage
You need to understand how the application’s data flow. Knowing the codes that influence different objects will help you design a serverless API that will prompt your application’s data usage.
Service Interactions
The next step is to map all the interactions between each microservice in your application. Learn the interdependencies in the application and how they will change after every endpoint is assigned its function.
Entry Points
Now it’s time to examine the entry points for your application. They include the crucial functions of the application; for instance, the API calls that the application’s frontend leverages to populate views that your users utilize to interact.
Data Migrations Planning
Lastly, you need to examine your data storage requirements before you start the process. Building on AWS Lambda is more likely to reap great benefits. However, its invocations incur charges on data transfers and compute usage.
Seems like an engaging process that can be frenzying if you have a tight schedule. Getting a top nearshore SaaS developer can help you maneuver through this smoothly.
Migration Process
The migrations process starts with breaking down each microservice into low and high-level functions. The granularity depends on how fast you want to move, and it gets difficult with complex communication.
Hence, you need to choose a breakdown approach that matches the complexity level of your application. You should also make sure the critical aspects of the business functionality are thoroughly tested by moving them first to the serverless architecture.
With nearshore outsourcing, you can have this done exceptionally to avoid problems when running your application. Besides, having someone skilled in this can save you much time and money.
So, what next after migration?
After migrating to a serverless application, you need to optimize communication, tackle resource serialization, and performance optimization. Most CTOs and CIOs find these tasks daunting since they have more duties to attend to. Thanks to nearshore development which does all these at a reasonable price.
Serverless, the Future of Software Development Cloud-Based
The cloud services field is fast-paced and ever-growing, with several service types. Consequently, there exists a progressive demand for higher capacity, resource, and computing resources. The serverless architect is one innovation that has been meeting all these demands.
Serverless cloud computing allows businesses to focus more on developing, managing and deploying their applications. This paradigm shift is essential in eliminating the tedious task of system administration.
