Microservices: A Beginner's Guide to a Modern Architecture
In recent years, microservices have emerged as a popular architecture for building large, complex software applications. This approach is known for its flexibility, scalability, and resiliency, which make it an ideal choice for modern software development.
In this post, we’ll take a closer look at what microservices are, their benefits, and some of the challenges that come with using them.
At San Diego Consulting Group, we believe each problem requires a unique custom approach to solve and provide value. We carefully evaluate our clients' needs and choose the best technology for each project. Microservices are a powerful tool for modern software development so let's unpack a bit here.
What Are Microservices?
Microservices are a software architecture style that involves building an application as a collection of small, independent services. Each service is designed to perform a specific function and can communicate with other services using APIs. This approach is in contrast to a monolithic architecture, where an application is built as a single, large system.
The idea behind microservices is to break down complex systems into smaller, more manageable components. By doing this, it becomes easier to develop, test, and deploy individual services. In addition, each service can be scaled independently, allowing for greater flexibility and efficiency.
Benefits of Microservices
There are several benefits to using microservices for software development. Here are a few of the most notable:
Flexibility:
Microservices enable developers to work on different parts of an application independently. This allows for greater flexibility in the development process, as changes can be made to individual services without impacting the rest of the system.
Scalability:
Because microservices are small and independent, they can be scaled up or down based on demand. This means that resources can be allocated where they are needed most, improving overall efficiency.
Resiliency:
If one microservice fails, it won't necessarily bring down the entire system. Other services can continue to function independently, which helps to ensure that the application as a whole remains operational.
Agility:
With microservices, new features and updates can be developed and deployed quickly. This enables organizations to respond more rapidly to changing market conditions and customer needs.
Challenges of Microservices
While microservices offer many benefits, they also present some challenges. Here are a few of the most common:
Complexity:
Because a microservices-based application is made up of many smaller components, it can be more complex to develop and maintain than a monolithic application.
Communication:
In order for microservices to work effectively, there must be a high degree of communication and coordination between different services. This can be challenging to achieve, particularly as the number of services grows.
Testing:
Testing can also be more complex with microservices, as each service must be tested independently as well as in the context of the larger system.
Top Providers of Microservices
There are several providers of microservices platforms, each offering their own unique benefits.
Here are 5 of the top providers:
Kubernetes:
Kubernetes is an open-source platform for container orchestration. It provides an infrastructure for running microservices and automating deployment, scaling, and management.
AWS Lambda:
AWS Lambda is a serverless computing service that allows developers to run code in response to events and automatically manage the computing resources required.
Microsoft Azure:
Microsoft Azure offers a wide range of services for building and deploying microservices, including Azure Kubernetes Service, Azure Functions, and Azure Service Fabric.
Google Cloud Functions:
Google Cloud Functions is a serverless compute service that allows developers to run code in response to events without having to manage servers.
Docker:
Docker is a popular platform for building and deploying containerized applications. It enables developers to package applications into containers that can be run on any system with Docker installed.

The San Diego Consulting Group has a team of experienced developers who work closely with our clients to ensure that their projects are completed on time and on budget. Our team is comprised of only the most competent people who are committed to excellence, teamwork, and the success of our clients.
All of our projects are managed out of San Diego California so our clients have a single point of contact in the US time zone for all of their needs.
We don't use CSM's so your account manager stays involved with you and your project manager all the way through. After all, one of the reasons you chose to work with your development partner is because you liked like your salesperson, why should you be forced into working with a pseudo-sales success manager who doesn't know you or your goals?
Our skilled designers and developers have the utmost integrity, openness, and honesty and will get the job done the right way.
