Understanding Microservices and Containerisation
Microservices and containerisation have quickly become the standard in software development over the past few years. But, just what do they mean? How do they work together, and why are they becoming so popular with tech departments worldwide?
In this blog post, we'll unravel all of these questions so that you can better understand how microservices and containerisation work and their benefits to IT professionals everywhere.
What is a Microservice Architecture?
Microservice architecture is a way of designing complex software applications comprising small and loosely coupled services. These services are independently deployable, each performing a single function representing a specific business capability. For example, micro front end architecture is a cutting-edge approach that allows teams to independently develop, deploy, and scale front-end applications, enabling seamless integration and enhanced flexibility in software development. Such an approach aims to make applications more resilient, cost-effective, and manageable.
By isolating related functions into individual microservices, any service can be updated or replaced without affecting the other parts of the application, allowing developers to focus on one component at a time and make updates quickly with minimal disruptions in the system. Furthermore, organisations can scale particular services to increase performance as needed or migrate modules between private and public clouds, maximising flexibility while optimising costs.
Microservice architecture is an integral part of digital transformation initiatives as it supports businesses in developing robust applications faster.
Understanding Containerisation
Containers are precious tools for developers that offer an innovative new way to package, deploy, and manage applications. Through application containerisation an organisation can streamline development processes. Furthermore, as containers can isolate an application and its dependencies to run in any environment, it can increase scalability and reduce costs.
The benefits of containers include more efficient use of hardware resources, faster software delivery cycles, improved security through greater isolation from external networks, and increased portability for applications throughout their entire lifecycle. As such, it's an area you shouldn't overlook.
But how can they help your organisation?
Benefits of Using Containerisation
Application containerisation offers multiple benefits to businesses. By using application containers, organisations can scale their applications and workloads quickly and effortlessly - making them ideal for running complex cloud operations.
Application containers also have an excellent portability feature, which enables developers to create a single package with all application components, such as libraries and dependencies, enabling easy deployment across multiple environments.
In addition to scalability and portability, containerisation allows organisations to realise cost savings by optimising their storage volumes according to their needs. Consequently, it will enable organisations to streamline processes at minimal cost, making them more efficient and flexible in the long run.
What are the Challenges of Containerisation?
Containerisation is becoming increasingly popular for organisations seeking to modernise their applications and services. However, as with other new technologies, it comes with its challenges. For example, from a security perspective, organisations must ensure they have sufficient protections to protect their containerised environments from malicious activity, such as network intrusion, malicious code injection and unauthorised access.
Because containers rely on multiple components - such as orchestrators and runtimes - which need monitoring with additional security considerations, organisations may find themselves dealing with an unexpectedly large number of moving parts requiring managing. Similarly, complexities are associated with deploying containers in an environment where applications must interact seamlessly. For this reason, organisations should ensure they have the necessary policies and infrastructure to manage container lifecycles and any software dependencies that might arise.
Ultimately, if done correctly, the adoption of containers can offer undeniable benefits from both a cost point-of-view and efficiency gains, provided organisations are ready for the challenges that come with it.
How to Use Containerisation in Your Development Workflow
Containerisation is an efficient and streamlined way to develop software. Development teams can quickly deploy applications across multiple environments by relying on software containerisation. This level of flexibility makes containerisation an excellent choice for any project.
To get the most out of this technology, consider different workflow areas that could benefit from container usage. Here are some tips for using containerisation in your workflow:
• Start by isolating application components in separate containers so that changes to one are not affected by changes to another, ensuring each feature has independent testing and management.
• Next, make sure the size of your containers is appropriate for the job; larger containers take longer to deploy and can incur more resource costs.
• Lastly, orchestration tools like Kubernetes can manage large deployments, monitor individual operation statuses, and roll out updates seamlessly.
With forethought and some upfront planning, it's possible to have a smooth container experience across your entire development environment.
Selecting the Right Platform for Your Applications
Selecting the right platform for running containerised applications can seem daunting. However, considering your specific needs and goals is the best way to make an informed decision.
Consider what questions you are trying to answer, such as which application or workload requires containers - or if you need to build custom or preconfigured images for deployment.
Additionally, consider your team's existing tools and resources and the environment that will host these applications to ensure that whatever platform you select can support them in either an on-premises or cloud setup. With this information, research available options and compare what each platform offers.
Finally, when choosing a platform for running your containerised applications, ensure it meets all your security and compliance requirements so you can rest assured.
The Final Word
Microservice architecture is a promising software development approach that helps address modern software development's complexity, such as scalability and cost-efficiency. Equally, containers and containerisation are two of the most critical components in a microservices architecture. They can help simplify development workflows and offer numerous advantages, such as portability and scalability.
However, there are some disadvantages to using containers in a microservice architecture, such as potential security vulnerabilities, so it's essential to consider this entirely before committing to the technology.
To ensure you're making an informed decision regardless of your choice between containers or traditional server-based hosting models, research all available options and properly evaluate which best fits your needs.
