WSO2 API Microgateway 2.6.0: Cheat Sheet
#ICYMI: What Is WSO2 API MicroGateway (MGW)?
It is a lightweight proxy for your APIs.
Core Features
* Security via OAuth2, JWT
* Throttling
* Usage metering (Analytics)
* Low resource usage (2CPU, 256 MB RAM)
* Fast bootup time
When to Use
* When there is unusual traffic for an API or a set of APIs, you can spawn an MGW to serve traffic during that period without impacting the performance of other APIs
* When there is a need to run a gateway in a lockdown environment that does not have connectivity to other API management components (e.g. Publisher, Store, KM)
* When deploying an API gateway within a microservices architecture where gateway acts as a sidecar to the main service (or API)
How API MGW Works
* API developers use the Publisher interface to create the APIs
* API admins publish this API
* API MGW will connect to the API publisher and generate a micro-gw runtime
How WSO2 API Microgateway works
How to Invoke an API
* Log into the developer-portal (Store) and subscribe to the API through an application
* Generate an access token (JWT or OAuth2 token)
* Send the request along with the token
e.g. curl -k -i -H “Authorization: Bearer ” https://goo.gl/5wBdvN
An Introduction to APIs for Product Managers
#ICYDK: What is an API? That’s a question that more and more folks are asking as APIs assume an increasingly important role in powering modern applications and infrastructure.
By now, virtually everyone who works in tech in some way has heard of APIs and might have a simple understanding of what an API is. But if your job doesn’t involve working in a technical way with APIs or the applications that run on them, your understanding of how APIs really work, and what it takes to create and manage an API effectively, is likely to be limited. https://goo.gl/6LwUpB
Removing the Integration Headache in M and A Deals
The merger and acquisition market is on track to hit record levels in 2018. According to Mergermarket, the first half of the year saw 8,560 deals recorded globally at a value of $1.94tn, with 26 deals falling into the megadeals category of over $10bn per deal.
The landscape is littered with unsuccessful mergers and acquisitions, companies that did not heed obvious risks that, in retrospect, were avoidable. Instead, dealmakers focused on the benefits of the transaction, such as prospects for a larger market share, competitive advantages, reduced costs, increased efficiencies, and more diversified products and services. https://goo.gl/NS7R45
