In planning for the future of a software development project, it’s vital to have a firm understanding of the underlying architecture that will shape the project’s trajectory. Specifically, business owners need to decide on an architecture that ensures agility, scalability, and performance. Among the front-runners for scalable solutions are two distinctive models: serverless and microservices.
The Microservices Model – A Brief Overview
The microservices architecture is, essentially, a decentralized application that has been partitioned into several modules, often referred to as services. Each of these services is tasked with executing a specific function. Generally, these services are specialized to perform a singular task exceptionally well.
The Serverless Model – A Quick Summary
Serverless architecture, as its name implies, eschews the need for your company to maintain its server space. Instead, a third-party vendor handles all the internal operations – storage, security, computing capabilities, among others – which could lead to significant cost reductions.
Key Differences: Serverless vs Microservices
Understanding the fundamental differences between these two architectures requires a detailed examination of several factors, such as functions, IT operations, cost, and runtime.
Functions
While both models have their unique sets of functions, the serverless model employs short-term functions that run based on specific conditions. Conversely, a microservices function is broader, often handling related processes simultaneously.
IT Operations
In the microservices model, the development team undertakes monitoring, deployment, support, and maintenance, whereas serverless architecture relies heavily on third-party vendors.
Cost
The cost of developing microservices tends to be higher initially, primarily because it demands several teams and meticulous planning. On the other hand, serverless architecture, with its shared resources and the absence of hardware specialists, is typically cheaper.
Runtime
Serverless functions have limited runtime, contingent on the provider’s specific limitations. Alternatively, microservices aren’t limited by runtime, storage space, or RAM, making them more suitable for complex long-term operations.
Combining Serverless and Microservices Architectures
The rapid evolution in technology has presented development teams with the opportunity to leverage both the serverless and microservice architectures concurrently. By hosting a set of event-driven services (microservices) on a third-party infrastructure (serverless), companies can significantly enhance their scalability, flexibility, and cost-efficiency.
Advantages of Adopting Serverless Architecture
Serverless architectures offer several benefits, including easy deployment, reduced cost, heightened scalability and flexibility, decreased latency, and Function as a Service (FaaS). It also frees companies from potentially risky investment in excessive server spaces by offering access to vast computing resources owned by large technology corporations.
Advantages of Adopting Microservices Architecture
Adopting a microservices architecture comes with its share of advantages, such as the decentralization of tasks, reduced risks, and most notably, scalability. This model aligns well with modern management methodologies like Agile and DevOps and fosters a culture of responsibility and ownership among small development teams.
