The combination of public and private keys are known as a key pair. You will use this key pair to securely access your instances using a private key. You can create a key pair using the Amazon EC2 console or the command line. After you create a key pair, you can use it when you launch your instance.

Amazon Web Services (AWS) – 1 – Basic Terms

Published December 3, 2019 By Brijesh Gogia

There are some common terms and topics which are true/applicable for any cloud based vendor. Below we will discuss some of these terms in simplest form.

Cloud Computing

Computing when used as a Noun means “the use or operation of computers”
Cloud in the technological term means some location away from your premise. Your premise is termed as “on-premise”

So, roughly speaking, the definition of “Cloud Computing” can be => “The use or operation of computers (servers, storage, network components etc.) which are stored somewhere else”

In more sophisticated language, Cloud computing is the on-demand delivery of compute power, database storage, applications, and other IT resources through a cloud services platform via the Internet with pay-as-you-go pricing

Integrated SOA Gateway (ISG) – 2 – Service Enablement in Oracle E-Business Suite

Published December 1, 2019 By Brijesh Gogia

We already described in earlier post what is web service. Service enablement is one of the “essential features” or “process flow” in Oracle E-Business Suite Integrated SOA Gateway. You can say it is that “magic ingredient” which allows native packaged integration interface definitions written in PL/SQL, Java, and other formats and stored in Oracle Integration Repository to be transformed into Web services.

“Service enablement” involves:

Generating service artifacts, such as XSD
To validate XML messages, WSDL or WADL to describe the Web service,
Deploying web services on an application server so that the services are available to clients over the Web.

Its interface is described in certain format which can be processed by machine.
WSDL is one kind of interface format which can be created using SOAP messages

Published November 10, 2019 By Brijesh Gogia

Jenkins is free tool and is considered one of the important tool for DevOps related activities. It is written entirely in Java language.

Before we move further we need to understand one key term “continuous integration/deployment”

What is continuous integration/deployment

You have a large team of 15 developers.
Code is changed and committed many times in a day
“Commit” means code will be “build” and tested
If “testing” is good, then build is tested for deployment
If “deployment” is good, you will plan for Production push
