Do you want to backup your data easily and securely, without spending hours or money on complicated tools or services? If so, this post is for you! I will show you how to use Kopia, a fast and secure open-source backup tool, and OCI, a scalable and cost-effective cloud storage provider, to backup your data in 10 minutes or less. OCI object storage is a cloud storage service that offers the following features: ...

A while ago, I developed a tool with the aim of assessing the actual performance improvement between different versions of PHP. Subsequently, I search to understand which AWS instance type was the most performant. Since AWS does not allow for custom sizing of CPU and RAM resources, I wanted to explore the differences among the various instance types and determine which one would be most cost-effective to choose. During the holiday season, I dedicated myself to expanding this project and doing the same analysis with OCI , Oracle Cloud Infrastructure. ...

In this article, we will leverage OCI’s capabilities to the fullest, embracing the following principles: Scalability Resilience Flexibility Security Automation The “loadfileintoadw” project is located in the same GitHub repository used so far to discuss OCI Function fn-examples . This example will help you understand how to integrate multiple OCI services and make the most of the cloud provider. We will simulate a series of weather stations that will write a CSV file with sampling data (temperature, humidity, etc.). The sensor will automatically upload the file to an Object Storage bucket. ...

Introduction to the most modern cloud database in the market Oracle Autonomous Database is a cloud database that uses machine learning techniques to automate its tuning, security, backup, updates, and other management procedures traditionally carried out by a DBA. Unlike a conventional database, Autonomous performs all these and other activities without the need for human intervention. Why use Autonomous? Databases contain critical business data and are essential for the efficient operation of modern organizations. DBAs are often busy with repetitive and manual database management and maintenance activities. As administration activities increase, the risk of human error becomes higher with catastrophic consequences. ...

After seeing how to create a custom image, in the previous case where we installed the Oracle client, now let’s try to use this custom image to connect to an Oracle database. We will make the most of the cloud capabilities. In this example, we will use the Infrastructure as Code (IaC) methodology to provide a real example of an easily replicable architecture for everyone. The “toautonomous” project is in the same GitHub repository used so far to talk about OCI Function fn-examples . The project’s README describes the infrastructure configuration procedure. ...

As we have seen from my other articles, it is possible to use the FN project with different programming languages using predefined container images, the officially supported languages are: go java Node.js ruby Python C# you can do it with the runtime directive, for example: fn init --runtime python test the command will produce a func.yaml file of this type 1 2 3 4 5 6 7 8 schema_version: 20180708 name: hello version: 0.0.1 runtime: python build_image: fnproject/python:3.9-dev run_image: fnproject/python:3.9 entrypoint: /python/bin/fdk /function/func.py handler memory: 256 However, in some cases, the predefined images are not sufficient, either for extra language support, extra drivers, or other missing tools. ...

The OCI Function service allows you to run code on infrastructure that you don’t have to manage. In this link I presented a basic example of an OCI function developed in Python. A very interesting feature is that functions can be automatically invoked by other services through an event, so we can also execute code in response to an action in the OCI cloud, or use a function as a link between multiple cloud services that can form a complex workload. ...

The OCI Function service allows you to run code on an infrastructure that you don’t have to manage, in a scalable and automated way. This concept is called “serverless” because the end user will no longer have to worry about managing any infrastructure to run his own code. OCI implements what is the FN open source project, the project has been integrated with Oracle cloud services and is based on the execution of code inside a container, therefore it can potentially support any programming language and any type of container on x86 architecture, moreover, it is not strictly linked with the Oracle infrastructure and you can easily switch between different FN environments. ...

Identity and access management is a crucial goal in a growing organization. In addition to the requirement to simplify user management and improve security, integrating with external services is becoming increasingly relevant. Oracle OCI offers a comprehensive service for managing identity and access called IAM with Identity Domains In the specifics: An identity domain is a container for managing users and roles, federating and provisioning of users, secure application integration through Oracle Single Sign-On (SSO) configuration, and SAML/OAuth based Identity Provider administration. It represents a user population in Oracle Cloud Infrastructure and its associated configurations and security settings (such as MFA). ...
