Orchestration: Allow the orchestration of multiple services calls into one API call. Monitor: Provides the ability to monitor API invocations.
Do I really need an API gateway?
If you don't have API Gateways, the client apps must send requests directly to the microservices and that raises problems, such as the following issues: Coupling: Without the API Gateway pattern, the client apps are coupled to the internal microservices.
Does API gateway do load balancing?
Load Balancing: The API Gateway can work as a load balancer to handle requests in the most efficient manner. It can keep a track of the request load it has sent to different nodes of a particular service. A gateway could be intelligent enough to balance load between different nodes of a particular service.

What is the difference between API and API gateway?
API is an acronym for Application Programming Interface. It is a set of definitions and protocols that allow technology products and services to communicate with each other via the internet. An API Gateway is used as the entry point for client requests to an API.

What is the most important reason why would use API gateway gateways over commodity gateways?
An API gateway provides a clean interface for clients to interact with, making your system easier to use and therefore more attractive in a competitive marketplace.
What is an API gateway?
For most microservices-based architectures, it makes great sense to consider using an API Gateway that can act as a single-entry point and can provide additional features like authentication, monitoring and load balancing.
What is an API?
Application program interfaces (API) are sets of routines, protocols, and tools for describing how software applications and components should interact with each other. They are the key driver in today’s economy for integrating with an ecosystem much larger than most companies can build on their own.
What is an API gateway?
An API gateway is programming that sits in front of an API (Application Programming Interface) and is the single-entry point for defined back-end APIs and microservices (which can be both internal and external). Sitting in front of APIs, the gateway acts as protector, enforcing security and ensuring scalability and high availability.
Why is gateway important?
A gateway is critical to help ensure great performance, high availability and elastic scalability of APIs by enabling enterprises to initiate delivery with uniform supporting services, including traffic management, transformation and system integration.
The Organizational Benefits of an API Gateway
These are extraordinary times for building great products. Enterprise leadership teams are debating build vs. buy approaches. Legacy macroservices (or monoliths) are being refactored into microservices. Product managers are becoming more & more technical. And the single pattern fueling each of these conversations is the API Gateway.
What is an API Gateway?
API Gateways are a tool in the API management arsenal that brokers communications between enterprise applications. These applications could be consumer apps driven by APIs or the APIs themselves talking to each other as in the case of microservices. Their goal being to simplify & focus these communications at scale.
Who Benefits?
The introduction of the API Gateway pattern has evolved many aspects of software development. In principle, it provides engineering initiatives much needed visibility into backend services. But more than that, it provides independence. Independence for product teams to think freely about the complete consumer experience.
The Enterprise Architects
Scale with purpose on an API gateway. Smart development organizations have adopted domain-driven design (DDD) standards which target engineering efforts towards specific problem areas adding velocity and focus. Exposing these functions as endpoints has never been easier for the rest of the organization to access.
The Partners
Become a more attractive technology partner with an API gateway. As powerful brands expand their offerings and make more promises to their customers there is even more of a need to partner with other technology providers. An API gateway can make responsibly sharing enterprise data easier and on-boarding new partners faster.
The Engineers
An empowered developer has more visibility with an API gateway. In fact, as each service is registered a contract is created and published in most cases to every contributor. In addition to detailed documentation for each individual API you now have clear transparency about how it plays in the broader context of the organization.
The Product Manager
Microservices becomes more of a reality for your organization with an API gateway. Domain-driven design has been a pattern of smart developer organizations for years but most never get the chance to step into true microservices because traffic between groups next to impossible to implement.
What is an API gateway?
An API gateway acts as a proxy for your application’s microservices, exposing the public-facing API endpoints, routing incoming client requests to the relevant services, transforming them as required and aggregating the response data before sending the response to the client.
Why should I have multiple API gateways?
As the interface that consumers of your system will interact with, an API gateway should be designed to meet their needs. If your system serves multiple types of clients, it may be appropriate to provide multiple API gateways based on those types. This design, known as “backends for frontends,” allows different endpoints to be exposed as well as different security and traffic management policies to be applied.
What is a microservice?
A microservice-based system can consist of dozens or even hundreds of individual services communicating with each other via APIs. While it’s possible for a client – be that a web browser, application or IoT device – to make requests to the relevant microservice directly, this approach has a number of disadvantages.
Why do organizations use microservices?
Organizations are increasingly adopting microservices for the architecture’s inherent flexibility and scalability, but to fully realize the benefits of a microservices approach, you need an API gateway. A microservice-based system can consist of dozens or even hundreds of individual services communicating with each other via APIs.
Is API gateway a bottleneck?
Being the single point of entry for your system does not mean an API gateway should become a bottleneck or a single point of failure. For applications requiring high availability, setting up a cluster of API gateways with requests load balanced across them ensures a more resilient system.
What is API gateway?
However, what is an API gateway? An API Gateway is a software program that acts as the façade for Application Programming Interface. For defined microservices, the gateway provides a single point of entry. This is especially beneficial when the client uses multiple and incongruous APIs.
Why is API important?
This is especially beneficial when the client uses multiple and incongruous APIs. One of the primary benefits that an API offers to developers is the ability to encapsulate the internal structure of an API in various forms , depending on the requirement.
Does Amazon API gateway increase latency?

Does Amazon API require monthly subscription?
As with all the services included in AWS, the Amazon API gateway also provides you with the option of paying as you go. The service does not require any monthly or annual subscription. There is no startup or minimum cost; you only pay for incoming calls and data processed out. To implement the API gateway, you do not have to go through ...
Does Amazon API Gateway work?
The Amazon API Gateway supports multiple versions of an API allowing calling of the previous version even when the latest version has been published. The platform allows you to maintain custom domains for each API versions while the endpoints remain the same. This helps in an easy rollback to the previous version of API.
