Microservices, also known as the microservices architecture, is an architectural style that structures an application as a collection of loosely coupled services. In a microservices architecture, services are fine-grained and the protocols are lightweight.
The microservices architecture enables the rapid, frequent, and reliable delivery of large, complex applications. It also enables an organization to evolve its technology stack.
Each service, or 'microservice', is a self-contained piece of business functionality with clear interfaces, and may be independently developed and deployed. Services can be developed using different programming languages, can use different data storage technologies, and can be tested and deployed independently of other services.
A major characteristic of microservices architecture is the emphasis on decentralizing decision-making. This decentralized approach to building software fosters a sense of ownership and accountability that drives quality and productivity.
Microservices architecture involves the development of software systems that are separated into independent component services that can be developed, tested, deployed, scaled, and versioned independently.
Key principles of a microservice architecture include:
The architecture of microservices has a suite of enabling services usually managed by a 'platform team'. These include services for service discovery, external configuration, load balancing, synchronizing distributed data, etc.
The adoption of microservices has many benefits including the flexibility to design services for specific tasks, independent deployments, technology stack diversity, and scalability at the component level. Here are a few:
However, adopting microservices comes with its own set of challenges, including service integration and management, data consistency across services, performance overhead, and operational complexity.
Securing microservices involves securing APIs, network communications, and the software supply chain. While APIs and network communications are integral parts of microservices security, they're just the tip of the iceberg. The software supply chain includes everything from the source code and libraries to the container images, and is often the weakest link in security.
Every time a microservice is updated, there's a chance that a vulnerable dependency could slip into the code. This can then be exploited by attackers to carry out a supply chain attack. These attacks have been on the rise in recent years, causing immense damage.
Considering the fact that microservices may be developed using different languages and frameworks, managing security for each of them can be a complex task.
Socket, an advanced tool for detecting and preventing supply chain attacks, offers an effective solution to secure your microservices.
Unlike traditional vulnerability scanners that reactively scan for known vulnerabilities, Socket provides proactive security measures. It inspects packages in detail to understand their actual behavior, thus identifying and blocking any suspicious or potentially harmful activity.
With Socket, you can:
By assuming that all open source might be malicious, Socket changes the game, offering a proactive rather than reactive approach to securing microservices. This makes it an essential tool for any organization looking to adopt a microservices architecture.
