How KrakenD Steers the Fleet
As we traverse the evolving landscape of modern services architecture, the significance of an API Gateway cannot be overstated. At KrakenD, we are not just participating in this evolution but leading it. We have channeled our expertise into developing an API Gateway solution that is efficient, scalable, and perfectly tuned to meet the specific needs of the digital age.
What is an API Gateway?
Think of an API Gateway as the touchpoint that connects your clients to your backend services. It takes on the responsibility of request routing, composition, and protocol translation, all of which are integral to a microservices environment.
The increasing adoption of microservices has cast the API Gateway in a more prominent role. It now serves as the primary entry point that fields external requests and directs them to the appropriate services.
Why is an API Gateway Important?
A modern application in a microservices architecture is a conglomerate of numerous services that need to interact seamlessly. The API Gateway orchestrates this interaction by providing a single-entry point for all these services, bolstering security, and enhancing performance.
An API Gateway offers:
- Abstraction: By presenting a unified interface to clients, an API Gateway abstracts the complexity of underlying microservices.
- Security: It undertakes all security concerns, including authentication and authorization, safeguarding your sensitive backend services.
- Rate Limiting: The API Gateway controls the number of requests a client can make within a specific time, preventing overuse and ensuring service protection.
- Performance: API Gateways boost service performance via caching and other techniques.
The KrakenD Advantage
At KrakenD, we’ve pushed the envelope of API Gateway technology to create a solution that outperforms others in the market:
- High Performance: KrakenD’s superior design allows it to handle up to 70k requests per second from a single instance. By reducing the resources required to manage high volumes, KrakenD lowers the Total Cost of Ownership.
- Scalability: KrakenD’s stateless design eliminates the need for coordination or data synchronization and removes any central point of failure.
- Simplicity of Operations: KrakenD is easy to run and operate, thanks to its binary and a declarative config file. This design makes KrakenD agnostic to the deployment strategy, whether cloud, bare-metal, or hybrid.
- Features: More than just a network layer software, KrakenD operates at layer 7 (application layer) and offers advanced data aggregation, protocol transformation, and content manipulation.
- Modular and Extensible: Rather than being an all-in-one tool, KrakenD facilitates easy integration with your existing stack of specialized solutions and allows extension via Lua or Custom Plugins.
- Transparent Pricing: KrakenD’s pricing model is simple, stable, and predictable, not tied to traffic volume, calls, or APIs - a clear advantage over most commercial solutions.
Concluding Thoughts
The vital role of an API Gateway in the world of microservices is undeniable. With its unmatched performance, scalability, operational simplicity, feature-richness, and modularity, KrakenD stands apart as the API Gateway of choice for modern services architecture.
