Serverless Architecture

Is Serverless Architecture beneficial for everyone? Some factors need to be considered to get an accurate answer! Serverless Architecture may not be a suitable solution for an individual or a small or large-scale company that has existing applications with server infrastructure because of the loss of the invested capital. However, planning for migrating applications module by the module over time in Serverless Architecture will be accurate steps.

Applications that are small, can be deployed quickly, run stateless & periodically and have an event-driven functionality are simply the best fit for Serverless Architecture. Besides, new and modern applications can be hosted in the Serverless Architecture for adaptation with the new approach and to get real experience.

What Advantages & Benefits Serverless Architecture Gives?

The core theme behind the Serverless concept is to decrease time, complexity, snag, and eventually cost of operating a scalable and consistent server for a smart application. Before taking any decision regarding Serverless, one should drive into the basic gainful reasons of the Serverless Architecture.

Cutting Costs: Adopting Serverless is an effective approach to cut costs. Outsourcing the tasks of running servers, database, storage systems, or some logic reduce investment and operating costs of a server. It also reduces electricity consumption and human resources that save money. Besides, the ‘Pay for Use only’ method of Serverless technology minimizes costs spend on time when code is not running.

Avoid Maintenance & Explore Quality Time: Server infrastructure & maintenance is not required in a Serverless system. It enables developers or members of a development team to stay focus on coding rather than thinking about managing, patching, upgrading, and operating infrastructure. They simply can give quality time to develop front-end code to ensure business growth and customers’ satisfaction.

Improve Scalability, Flexibility & Latency: The understanding of traffic patterns is important for scaling traditional applications. The Serverless approach has worldwide access points and enables an application to be extremely accessible from any part of the world, scales up & down robotically as customers grow and as usage varies. This is also makes the application very flexible, easy to pivot, innovative, and faster compared to traditional methods.

What are the Drawbacks of Serverless Architecture?

Like any other technology, the Serverless approach also has some drawbacks that may be alleviated by taking remedial procedures.

Security is a Concern: A third party is involved in Serverless Architecture system that may create scopes for huge security concern such as DDoS attacks, SQL injection attack, inadequate monitoring & logging, unsafe data, broken authentication, architectural complexity or insecure third party dependency.

Vendor Lock-In & Reduce Control: Going Serverless, a company is losing entire control over the infrastructure. The application is running using a third party server. Code may need some correction or need to be rewritten considering the platform of the vendor and the existence of different types of APIs create problems. Therefore, Vendor Lock-In needs extra confidence for the third-party service provider.

Issues to be Considered before Going Serverless Architecture!

It is very important to choose an appropriate pattern which is suitable for the application because selecting an unsuitable architecture will destroy all the advantages of Serverless Architecture, create other hitches and sooner or later rise the cost! Therefore, following issues should be considered before going for Serverless Architecture approach.

o Nature of Data Architecture: Knowing about data architecture is extremely important before migrating and selecting a suitable platform or vendor options for the Serverless Architecture approach. Data store, manage, integrate, and manipulate processes depend on data types. Processing huge unstructured data requires a different model compared to process transactional data using a rational model.

o Skills of Staff: Analyze the nature of skill sets of the organization staff before going Serverless approach because they are the key to ensure business growth. Staffs need to have a clear understanding about the chosen Serverless platform. If require then train staff of the organization or hire required help.

o Go for Greenfield: Most update technology is used for Serverless Architecture system and updates very fast considering technological changes to ensure the best user experiences. It is better to think about Serverless using Greenfield approach to avoid the hazard of refactoring the existing application. Sometimes any minor changes in legacy apps may create gigantic ripple effects. So it is better to start fresh.
