3rd-Generation API Management: From Proxies to Micro-Gateways by Oracle ACE Director Luis Weir

Businesses today understand that, in order to remain competitive in a market dominated by digital disruptors[i], they must innovate and gain business agility and speed. To this end, organizations of all sizes are adopting cloud (SaaS, PaaS, IaaS)[ii] not only as the means to reduce TCO, but also as a vehicle to achieve digital transformation and customer centricity.

However, moving to cloud does not mean one cloud. Research suggests that organizations are opting for multi-cloud strategies[iii] as opposed to putting all their eggs in a single cloud vendor’s basket. This best-of-breed approach to cloud adoption means that on-premises monolithic system(s)[iv] (e.g., an ERP) and other on-premises applications are re-implemented in the cloud as discrete SaaS applications and integrated or extended with PaaS.

For those on-premises applications that either don’t have a cloud equivalent or simply don’t address the desired requirements, many organizations are also opting for application development in the cloud.[v] Microservices architectures[vi] have become predominant as an architectural style for implementing such cloud-native applications. To do this, a monolith is broken down into smaller pieces — each representing a business capability — and then implemented as a fully decoupled service (microservice),[vii] typically in PaaS.

As cloud adoption continues, information inevitably becomes more and more federated, not only across many different SaaS and PaaS applications (from different vendors), but also across many on-premises systems.

In order to achieve digital transformation, an organization must first either adapt or enhance its existing (on-premises) IT systems or attempt to replace them with modern ones (probably in the cloud), so products and services can be offered digitally via multiple channels (web, mobile apps, kiosks, partner online stores, bots, etc.).

Digital transformation makes co-workers more productive by enabling them to execute business processes whilst on the move through a seamless journey delivered by different device interactions.

It also enhances an organization’s partner ecosystem by giving them on-demand access to relevant business data and providing the means to execute business transactions electronically.

However, none of the above are possible if access to core business information assets is not availableÑand with information becoming federated, access can be a big problem.

Integration platform as a service (iPaaS)[viii] solutions address this issue. Their selling point is their ability to connect to any cloud and/or on-premises system and deliver the access required. A robust iPaaS platform should be capable of connecting to any cloud and/or on-premises application to deliver seamless access to information via RESTful Application Programming Interfaces (otherwise known as Web APIs[ix]).

The use of APIs as the means to deliver standard, consistent and secured access to information enables multi-channel applications to consume the assets they need when they need them. Read the complete article here.
