What is Oracle?
Its database is also known by the name Oracle. It is a multi-model relational management system that supports enterprise grid computing and data warehousing.
The database is currently available in five editions, each based on its features.
- Standard Edition One: This edition is for highly branched or single-server applications with limited features.
- Standard Edition: This edition includes all the features of Standard Edition One. It also offers greater machine support and Oracle Real Application Clustering service.
- Enterprise Edition: This edition includes features such as security, performance, scalability, availability, and other essential functions that are required for high-critical applications that involve online transaction processing.
- Express Edition: This is the entry-level edition. It's free to download and install, manage, develop, and deploy.
- Personal Edition: This edition includes the Enterprise edition features, except for Oracle Real Application Clustering.
Features
To meet the needs of database management, an Oracle database has the following features:
- Scalability, Performance, and Scalability: Features such as Real Application Clustering or Portability allow a database to be scalable according to its usage. Oracle considers it necessary to maintain data consistency and concurrency in multiuser databases.
- Availability: Real-time apps require high data availability. High-performing computing environments can provide 24/7 data availability. Data is always available, even during planned and unplanned downtimes.
- Backup & Recovery: This layout provides complete recovery capabilities to recover data from nearly all failures. The database must be reconstructed quickly in the event of a failure to ensure high availability. While the affected parts are being recovered, there is still unaffected data.
- Security: Data security is always a top priority. It offers mechanisms to restrict data access and usage. Authorization and editing of user actions can be used to prevent unauthorized access.
What is the Oracle database?
A relational database management system (RDBMS) from Oracle Corporation is called Oracle Database. The history, features, and editions of the Oracle Database will all be covered in-depth in this article.
Let's first understand the database before we talk about Oracle.
A relational database management system is the Oracle database. Other names for it are OracleDB or Oracle. Oracle Corporation is in charge of its production and promotion.
Together with other engineers, Lawrence Ellison created it in 1977. It is one of the most used relational database engines for storing, organizing, and retrieving data on the IT market.
Oracle is Important
One of the first businesses to provide database management solutions is this one. It has always been centered on enterprise demands while also taking the most recent technological advancements into account.
It often adds new features to its goods. The most recent Oracle database, 19C, is available via Oracle Cloud. You can select the database edition that best satisfies your demands and obtain an affordable solution.
Benefits
We've already discussed the database's features. These features give Oracle an advantage over its competitors. We will now look at the benefits.
- Performance: The system has the principles and methodologies to ensure high performance. Performance tuning can be implemented in the database to quickly retrieve and alter data, which will improve query execution speed and, thus, application operations.
- Multiple Database: This database allows you to manage multiple instances of a database on one server. It offers Instance Caging to manage CPU allocations on the server that runs the database instances. To manage multiple instances of services, instance caging is used in conjunction with the database resource manager.
- Editions: We have discussed the benefits of Oracle's various editions. Users can choose the edition that best suits their needs. If their needs change, they can easily update the edition. You can get the express edition database for absolutely nothing if you are interested in learning and doing some hands-on Oracle.
- Clusters: Real Application Clusters provide high data availability. The database with RAC offers many advantages over traditional databases servers:
- Scaling the database across multiple instances
- Load balancing
- Redundancy of data and availability
- Flexibility to increase processing power
- Failure Recovery: RMAN (Recovery manager) is an Oracle DB feature that allows you to recover and restore database files from downtimes or outages. It supports continuous archiving and online backups. SQL* PLUS can be used for recovery. This is called user-managed recovery, and it is supported by it. To add user-managed backups, there is an export utility in the database.
- PL/SQL - The database supports PL/SQL extensions for procedural programming.
Why Do We Use Oracle?
It is a database management product. A database is a collection of organized information. Database management systems store the data and provide high-performance, authorized access, and fail-recovery features.
It is a simple software solution that manages databases from personal to enterprise-level applications.
What is DevOps?
DevOps is a continuous integration/continuous delivery (CI/CD) service that automates the delivery and deployment of software to Oracle Cloud Infrastructure (OCI) compute platforms.

Cloud Shell
Oracle Cloud Infrastructure (OCI), Cloud Shell, is a web-based terminal that can be accessed from the Oracle Cloud console.
Cloud Shell is available for free (within the monthly tenancy limits) and allows you to access a Linux shell with a pre-authenticated Oracle Cloud Infrastructure CLI and Ansible installation. Also, it provides other useful tools to follow tutorials and labs on Oracle Cloud Infrastructure. Cloud Shell is available to all OCI users and can be accessed from the Console.
Your Cloud Shell will appear in the Oracle Cloud Console as an active frame. It will remain active while you navigate to other pages of the Console.
Cloud Shell offers:
- A temporary machine that can be used as a host for Linux shells. It is pre-configured using the OCI Command Line Interface, CLI, and other useful tools
- 5GB storage space for your home directory
- The Console keeps a persistent frame active while you navigate to other pages
How Cloud Shell Works
The Cloud Shell machine runs a Bash shell and is accessible through the OCI console. Cloud Shell includes a pre-authenticated OCI CLI that is set to the Console home page region.
It also contains up-to-date utilities and tools.
Cloud Shell includes 5GB of persistent storage to store your home directory. This allows you to make small changes and then return to Cloud Shell to continue your project.
Cloud Shell is available for free (within the monthly limits of your tenancy) and does not require any setup or prerequisites.
Cloud Shell comes with a VM that is pre-configured for you. It executes in your tenancy, so it doesn't consume any resources. Your shell runs on an Oracle Linux OS.

Use Oracle Cloud Infrastructure DevOps Services to build a continuous integration, deployment, and monitoring pipeline
For cloud-based applications, it is important to have your software delivered quickly. Oracle Cloud Infrastructure (OCI), DevOps, provides a Continuous Integration & Deployment platform (CI/CD) for developers.
This allows them to quickly build, test, deploy, and maintain software and applications on Oracle Cloud.
OCI DevOps builds and deployment pipelines decrease change-driven errors. Customers spend less time building and repairing issues.
The software can be rebuilt, tested as changes are made, and any adverse effects detected early.
This service provides private GIT repositories for your code storage and connects to external code repositories that can hold configuration files and source code.
Because build processes depend on intermediate artifacts (modules and packages), they can also be used with Oracle's container and artifact repositories. OCI DevOps can be used to streamline the software delivery lifecycle, whether you are migrating workloads from on-premises or another cloud or you are developing new applications on OCI.
OCI DevOps is a tool that allows you to create artifacts for deployment in multi-cloud or hybrid environments.
Architecture
This reference architecture outlines all services and configurations required to build, test and deploy a Node.js sample web application.
Terraform deployment also includes the creation of pipelines and repositories. A DevOps repository hosts the application source code. The repository allows the user to commit the code, which triggers a build pipeline.
To develop, test, and produce a container image containing the most recent version, the build process adheres to a predetermined flow. The container registry stores the build output as an image. The most recent version of the application is then deployed using a deployment pipeline that uses the image created from the container registry as an image and a Kubernetes.
The provided pipeline doesn't address issues such as unit testing and code quality analysis using static code analysis or linter tools.
Take Into Account
These are the points to consider when you deploy this reference architecture.
- DevOps allows deployments to OKE and Compute hosts.
- For instance, group deployments of Compute instances and Linux hosts only are supported.
- DevOps artifacts must be stored in either an OCI container image registry repository or an OCI artifact registry repository.
- It is a good idea to group all applications and their microservices together into one project.
OCI Cloud Free Tier
Oracle Cloud is a free platform that allows you to build, test and deploy applications.
Arm Ampere A1 Compute has been added to the Always Oracle Cloud Free service. You can apply for OCI Arm Accelerator to help with large-scale Arm development projects.Oracle Cloud is the best choice if you're looking for a powerful server at a low price.
Over the years, I have used many cloud computing products, including Amazon Web Services, Microsoft Azure, and Google Cloud Platform.
