What is an API Gateway?
Jul 22, · A gateway is a data communication device that provides a remote network with connectivity to a host network. A gateway device provides communication to a remote network or an autonomous system that is out of bounds for the host network nodes. Gateways serve as the entry and exit point of a network; all data routed inward or outward must first pass through and communicate . noun an entrance or passage that may be closed by a gate. a structure for enclosing such an opening or entrance. any passage by or point at which a region may be entered: New York soon became the .
API gateways are a lot like a multi-lingual traffic cop, who not only knows where people want to go but also speaks their language, no matter what country they come from!
As a point-of-entry for requests for application services sent by end-user applications, gateways sit between APIs Application Programming Interfaces and the application services running on a server. Instead of the APIs sending requests directly to individual services, they go through the gateway, i. APIs that receive authorized access from the gateway is then directed to a range of services.
Here are some of the most common services:. During the process, the gateway translates the various protocols used by the APIs and then directs each request to the appropriate application service. Gateways invoke backend service requests and compile the results. Since developers update API gateways when adding and removing services, the update process should be lightweight, without putting a drain on how long gangrene to cause death gateway CPU and memory.
This allows the gateway to keep functioning properly as changes are made. API gateways include several functional components. Access Control manages which APIs can connect to each application service and the rules for how data requests are handled. This ensures that only authenticated user applications can connect to back-end services.
Another key function is Rate-Limitingwhich reduces the load on APIs to prevent misuse by permitting only a certain number of requests at one time. In some cases, higher rate limits are how to make a small igloo for a school project, such as services offered to customers. Threat Detection is also key. This provides protection against hackers who try to upload malware, SQL injection, and other forms of cybercriminal activity what is meant by gateway as DDoS Distributed Denial-of-Service attacks.
From a performance standpoint, Auto-Scaling handles spikes in activity while High Availability allows gateways to automatically failover to another gateway in the event of a system crash. This is particularly important for maintaining access to mission-critical application services. This requires replicating API gateways across multiple data centers. In addition to making business continuity possible, replication gives you the ability to provision application services from the multiple data centers, thus providing lower latency to end-users.
The gateway organizes requests processed by the microservices architecture to create simplified experiences for end-users. The gateway achieves this by taking multiple requests from an end-user application and turning them into just one to reduce the number of round trips between the end-user application and the microservices. For IT teams that use the DevOps approachdevelopers can use microservices to build and deploy applications in an iterative way, which is key since APIs are one of the most common ways that microservices communicate.
On the Ops side, cloud environments with a serverless model depend on APIs for provisioning infrastructure. Security is another key API gateway use-case. You can set policies on the gateway to allow or deny access to APIs and for specified IP addresses and virtual private network endpoints.
If the gateway is not managed well or configured what to write on a christmas card for your boyfriend, it could cause a bottleneck.
Depending on factors such as the scale of the traffic flowing through the gateway, it may get overwhelmed by the number of API requests for application services. Gateway performance can also be impacted by the performance of individual services and network latency. Situations like these call for load balancing and rate-limiting as described above. Cyberattacks can also degrade gateway performance, which makes threat detection essential.
You also want the gateway to integrate easily within your current technology stack, and it should provide a smooth migration path to other gateways— just in case you change gateway platforms in the future. For businesses with cloud environments, look for a provider that offers gateways with managed services so it will be easier to monitor and maintain your APIs and keep them secure.
The leading provider gateways also support containerization, serverless workloads, and web applications. Other key features to look for include traffic management, access control, throttling, and API version management.
Find a good one and you will be able to handle hundreds of thousands of concurrent API calls. When a request comes in, the gateway knows exactly which service to direct the request to and how to translate the request into a language the application service will understand.
This capability to direct and translate makes things easier for software developers as they code APIs and application services. Most importantly, API gateways make things easier for customers and internal end-users. When they submit a request to an application that invokes multiple services, the gateway efficiently brings all the requests together and returns a unified, multi-service response.
That means customers and end-users both get the information they need quickly and can transact business faster!

What Does Gateway Mean?
Nov 14, · A gateway is the most important feature of a router. Routers are the most common type of gateways. In some cases, such as in a residence that uses dial-up internet access, the gateway is a router at the internet service provider' s location. This has become increasingly less common as dial-up access declines in popularity. Jun 06, · A gateway is a network node used in telecommunications that connects two networks with different transmission protocols together. Gateways serve as an entry and exit point for a network as all data must pass through or communicate with the gateway prior to being routed. Sep 01, · A gateway is a node in a computer network that serves as an entrance to another network. A node is a processing location where data stops for either transporting or reading. For example, a computer or modem is a node, whereas a computer cable isn’t.
A camper is a video gamer who finds a strategic spot within a level and waits there for players, game-controlled enemies or choice items to appear. This strategy is known as camping. Camping is most popular in first-person shooter FPS games, but depending on the game being played, it is usually View full term.
Generally, a router is configured to work as a gateway device in computer networks. Any network has a boundary or a limit, so all communication placed within that network is conducted using the devices attached to it, including switches and routers.
The gateway or default gateway is implemented at the boundary of a network to manage all the data communication that is routed internally or externally from that network.
Besides routing packets, gateways also possess information about the host network's internal paths and the learned path of different remote networks. If a network node wants to communicate with a foreign network, it will pass the data packet to the gateway, which then routes it to the destination using the best possible path.
