ICS Pricing – ICS Definitive Tip #9 by Phil Wilkins

ICS pricing is based on two aspects – the number of connections and the number of messages processed.  But what constitutes a connection?  What happens if I exceed the number of messages or connections?

Number of Connections

The overall model for ICS pricing is on page 34 of Oracle Platform as a Service and Infrastructure as a Service – Public Cloud Service Descriptions-Metered & Non-Metered. The key definition for a Hosted Connection is on Page 9 of this document.  The critical wording for the connections is:

A Connection is counted per unique application, data source, third party software, Oracle software, Web Service or REST end point to which the Oracle Integration Cloud Service is connected. SOAP or REST Web Services that have the same base URI (combination of host and port) are counted as one Connection.

So you can define for example two ICS connections (one in and one out for example, or one per operation) to the same service aslong as the basic part of the URL e.g. icsallpurpose-xxxxxx.integration.us2.oraclecloud.com  is the same. The ports will typically only become a countable to the same URL if you use different protocols e.g. HTTP, HTTPS, FTP. This simply comes down to the fact different protocols typically use different ports.  But, if I daisy chained integrations within the same ICS instance; then assuming they are all HTTPS calls they would only consume 1 connection. This is regardless of how many different connections created to provide the full path.  This is also important as when transitioning versions of end points you may need the current and previous endpoints available, which within this model would count as the same connection as typically the version identifier is in the subsequent path.

Registries: Use Cases for API Management and Microservices by Phil Wilkins

Microservices and new 3rd-generation API Management capabilities are very natural technical partners. A (micro)service provides the execution logic for a single capability and 3rd generation API Management provides the means to control the exposure of each service to the outside world, and potentially between the (micro)services as well. Luis Weir’s article, 3rd-Generation API Management, explains the evolution of the API Management capability, and what the 3rd generation offers that makes API Management mesh well with (micro)services. For this article, though, we are going to explore the role of registries in a (micro)services environment and ultimately their relationship to API Management. We aren’t going to dive deeply into any specific solution, although we will reference some of the better known options, and provide links to where you can dig in further.

You’ll note I have referred to microservices as (micro)services. This is very deliberate, and possibly contentious.Microservices are typically associated with certain technologies such as Docker and lightweight app containers such as Tomcat, but from my view point if you’re going to be a purist about microservices, then (as with SOA) you need to think about the design paradigm and the principles—NOT the technologies. It is with this view point we often have to work as, unless you’re fortunate to be working in a services organization that is very enlightened or just plain fortunate, the decisions and constraints you have to work with will mean you need to make some pragmatic decisions. An organization that has made heavy investment in WebLogic licensing isn’t likely to be comfortable in giving it up—but this doesn’t mean you can’t adopt a microservices approach, although certainly you need to mitigate risks that using WebLogic can create when adopting the architecture. Secondly, the concept of registries isn’t unique to microservices; in fact, some of these solutions have origins in solutions such as Big Data/Hadoop offerings, for example.

To underline my point, Gartner has started to talk about mini- or micro-apps as a flavor of microservices. The essence of this is the application of microservice principles but in a more pragmatic manner—not every organization needs hyperscaling and super elasticity like the poster children of microservices (e.g., Netflix and Uber). But we all do need the means to easily manage the addressing of services.

To understand the role of a registry, we need to step back and understand some of the ideas underpinning microservices. So let’s just recap: Read the complete article here.

How Capgemini can enable the new Oracle API Management platform by Mark Albon

As the tendency continues for organisations to adopt not one but multiple cloud vendors, information has never been more federated. Real time access to such assets via APIs has therefore become a priority for our customers. Oracle API Platform Cloud Service delivers a pure-play 3rd generation API solution capable of creating and managing APIs that run in any vendor’s cloud and/or on-premises –whilst keeping the entire platform operations and API lifecycle central in the Oracle Cloud.

This flexible architecture means that we can create robust solutions for our customers that really puts them in the driving sit when it comes to managing access to information via APIs –regardless of where they are. The incorporation of Apiary into the platform, only makes it better as developers also get the tools they need to ensure that those APIs are well designed, documented and are easy to consume.

My first experience with Oracle API Platform Cloud Service – part 1 by Milco Numan

In the first part of this two part blog post, I will describe the use case for which we used Oracle API Platform Cloud Service (shortened to APIPCS from now on) as an outbound API Gateway, offering lookup services and centralizing outbound access. This part will also describe a simple Node.js microservice we deployed to Oracle’s Application Container Cloud Service to perform the translation of an internal identification into the API key required by the external API.

The second part of this blog will elaborate on the actual creation of the API definition in APIPCS, the invocation of the microservice using Groovy scripting and the testing of the external API using APIPCS.

Introduction

At a customer, for a proof of concept last year, I have been working with an exiting new Cloud Product from Oracle: API Platform Cloud Service, or APIPCS for short. In this blog, I will not go into architectural details on why you could, should or must use an API Manager of API Gateway. Nor will I be elaborating on all functionality or features of Oracle’s implementation of the product, since they’re perfectly capable of doing that themselves.

Basic Scenario

In the use case encountered at this specific customer, the requirement existed to not use the API Gateway as an inbound Gateway, but rather to use the API Management solution as an outbound gateway. The rationale for this setup is to provide a single outbound gateway through which REST services can be invoked where internal identifications can be translated into different kinds of external identifications, known to the outside world. The former may be thought of as (internal) applications, or perhaps even customer identifications stored in an internal system. The latter category then may relate to API-keys required by the external partner, or even OAuth2 tokens. Read the complete article here.
