Microservices, which involve disassembling complicated programs into more manageable, autonomous parts, are gaining popularity because they have several advantages over conventional monolithic architecture.

What function does cloud computing serve in microservices, then? In this article, we'll examine how cloud computing enables the creation and implementation of microservices and how it might assist businesses in more successfully achieving their objectives. We will explore the numerous ways that cloud computing and microservices are a natural fit, from the benefits of cloud-based storage and computational capacity to the advantages of a highly scalable and flexible infrastructure.

Let's dive right in -

Understanding Microservices Architecture

A software architectural style known as microservices divides an application's codebase into a number of smaller, autonomous services. These services can be developed, deployed, and managed individually, providing greater flexibility, scalability, and shorter development cycles. They communicate with one another using industry-standard protocols like HTTP.

Advantages of Microservices

  • Scalability: By scaling individual components, microservices can handle a large amount of traffic.

  • Resilience: Microservices can be fault tolerant and can keep working even if one of their components malfunctions.

  • Flexibility: Because microservices can be created, deployed, and managed individually, adding new functionality is simpler.

  • Independent Deployment: Teams can work on different system components at the same time and deploy them independently without affecting the other system components.

Challenges faced in Microservices

  • Complexity: Microservices increase the architecture's complexity, which makes it challenging to manage and monitor.

  • Operational Overhead: Compared to a monolithic architecture, managing and deploying microservices requires more resources.

  • Latency: Performance can be impacted by a delay, which can be added to the system by inter-microservice communication.

  • Inter-service Communication: Microservices must communicate with one another, which can cause dependencies and integration problems.

Understanding Cloud Computing

Cloud computing is like a big neighborhood library. Imagine you have a library card and can borrow any book you want, anytime you want, without having to keep all the books at your own house.

Similar to this, cloud computing allows you to use computer services like data storage and design implementation through the internet without having to own every piece of computer hardware and software.

And just like how different books are organized in different sections of the library, different services are organized into different types of cloud computing, like Infrastructure as a Service (IaaS), Platform as a Service (PaaS), Software as a Service (SaaS), and Function as a Service (FaaS).

Cloud computing is a technology that enables the delivery of computing services—including servers, storage, databases, networking, software, analytics, and intelligence—over the Internet (“the cloud”). You can access these resources on remote servers on the internet in place of using your computer's hard drive and RAM to store and run the software.

Advantages of Cloud Computing

  • Scalability: The ability to add or remove resources as necessary.

  • Lower operating costs and the absence of initial infrastructure investments are huge savings.

  • Accessibility: Any device with an internet connection can remotely access data and applications.

  • Flexibility: The capacity to combine and pair services as required, in order to accommodate various workloads.

  • Disaster recovery is also another benefit where you can quickly restore data and applications in the case of a catastrophe.

Types of Cloud Computing

  • Infrastructure as a Service (IaaS):  Servers, storage, and networking are all included in infrastructure as a service (IaaS), which gives consumers access to virtualized computing resources. Customers can host their own apps and data using these resources. Amazon Web Services (AWS), Microsoft Azure, and Google Cloud Platform are a few IaaS providers.

  • Platform as a Service (PaaS): It offers a whole platform for the creation, operation, and management of applications so that users don't have to be concerned with the infrastructure itself. Without having to handle the underlying infrastructure, customers can concentrate on creating and delivering their applications. PaaS vendors include Heroku, Google App Engine, and AWS Elastic Beanstalk, as examples.

  • Software as a Service (SaaS): This model gives users online access to software programs. Installation, maintenance, and upgrades are taken care of by the supplier, so customers don't have to. Salesforce, Office 365, and G Suite are three examples of SaaS providers.

  • Function as a Service (FaaS): This is a cloud-native computing service that enables users to run their code in response to events like new files being added to a storage system or data being changed in a database. Functions are perfect for performing specialized tasks like image processing or creating thumbnails since they are stateless, momentary, and event-driven. AWS Lambda, Google Cloud Functions, and Microsoft Azure Functions are a few examples of FaaS providers.
