Definition: The practice of using a network of remote servers hosted on the internet to store, manage, and process data, rather than a local server or a personal computer.
Cloud computing is a way of using the internet to access and use computing resources, such as storage and processing power, that are not located on your own device. Instead, these resources are provided by remote servers that are managed by cloud service providers. You can use cloud computing to store your files, run your applications, or perform various tasks without having to buy or maintain your own physical hardware or software. You only pay for what you use, and you can access your resources from anywhere and at any time.
In other simple words, Cloud computing is like renting a car instead of buying one: you don’t have to worry about the maintenance, you can choose the model that suits your needs, and you can return it when you’re done.
Cloud computing services are providers that offer various resources and capabilities over the internet, such as storage, computing, networking, databases, analytics, machine learning, and more. Cloud computing services can help businesses and individuals to reduce costs, improve performance, enhance scalability, and access applications from anywhere.
There are many cloud computing services available in the market, but some of the most popular ones are:

Oracle Cloud: Oracle Cloud is a late entrant to the cloud market that offers more than 50 services across different categories and regions. Oracle Cloud is used by many customers, especially in the database and enterprise applications segment, to leverage their existing Oracle investments and expertise. Oracle Cloud has a strong differentiation in its autonomous database, cloud infrastructure, and cloud applications.
Oracle Cloud Infrastructure (OCI)
Just like AWS/Azure/Google , Oracle has its own Cloud platform – OCI . And to capture market, they’ve all time free tierprograms targeting developers and individuals & small business.
OCI is a cloud platform that offers a wide range of services for various use cases. OCI has some advantages over other cloud providers, such as consistent pricing, performance, security, and customer service. OCI also has an Always Free tier that gives you access to a set of resources that are free for the lifetime of your account.
Here is an article that I wrote on Oracle Cloud Infra services, their Always Free services, and how they compare to other cloud services. And disclosing a secret this blog itself running on OCI’s free tier!
What is Oracle Cloud Infra (OCI) ?
Oracle Cloud Infra (OCI) is a set of cloud services that enable you to build and run a variety of applications and workloads in a highly available, secure, and scalable environment. OCI offers more than 100 services across different categories, such as compute, storage, networking, database, analytics, machine learning, containers, and serverless. OCI also provides hybrid and multicloud solutions that allow you to extend your on-premises infrastructure to the cloud and connect to other cloud providers.
Always Free tier
One of the attractive features of OCI is its Always Free tier, which gives you access to a set of resources that are free for the lifetime of your account. Yes, OCI Always Free tier is a feature gives you access are free for the lifetime. These resources include:
Compute: This is your computer processor. Just like AMD/Intel , you can choose from the options provided for you. Whatever case it has : Two AMD Compute VM’s and up to 4 instances of ARM Ampere A1 with 3,000 O CPU hours and 18,000 GB hours per month.
You can create multiple combination of compute instances based on the 200 GB block volume.
You can provision the compute with your choice of Operating Systems : Ubuntu Linux, Oracle Linux, SuSE Linux , Windows
Once the above compute ready, you can SSH and gain your root access! Install whatever you want – Setup LAMP (Linux/Apache/MySQL/PHP) to run a website/apps , Or spin up a WordPress blog or even setup your own cloud by installing the NextCloud app ( And these are just clicks away in your console)
Block Storage: This is the storage system comes with your account. By default it has free 200 GB of storage aka block volume. Please note every compute you create as mentioned above will demand minimum of 47 GB storage. So technically, you can have maximum of 4 compute ( 4 x 47 GB ~ 200 GB). Boot Volume vs Block Volume – Boot volume is integrated with compute instance! But Block volume is additional volume and you may treat this is your external HDD storage.
When you Terminate an instance, the block volume will be avail for you. Per documentation: When you create a compute instance, the default boot volume size for the instance is 50 GB, which counts towards your allotment of 200 GB. You can customize the instance’s boot volume size up to 200 GB; however, this will use up your full allotment of storage for Always Free Block Volume resources. Also, because the minimum boot volume size allowed for compute instances is 50 GB, launching four instances will use all your Always Free Block Volume resources. Alternatively, you can launch one instance with the default boot volume size of 50 GB, and then create and attach a 150 GB block volume to expand the storage capacity of the instance. ie 4 x 50 GB or 1 x50 GB +150 GB
Not only the plan comes with Block volumes, but they offer Free Backups as well (Five total volume backups)
Database:
Two Oracle Autonomous Databases with powerful tools like Oracle APEX and Oracle SQL Developer – Free limit 20 GB
Buckets – Object and Archive Storage – Similar to S3 buckets in Amazon realm. OCI offers Free 20 GB of storage where you can store/retrieve objects like media which may consume more space but need infrequent access
Five certificate authorities (CAs) and 150 certificates
With these resources, you can run small-scale applications, test new technologies, or learn new skills without worrying about costs or time limits. You can also upgrade to paid services at any time if you need more capacity or functionality.
OCI Always Free tier is a great way to get started with the cloud or explore new possibilities without any cost or risk. Compared to other cloud providers, OCI offers more resources, more flexibility, and more compatibility for your cloud needs.
You can learn/experiment with technology/tools like Python, MySQL and much more.
Personally I’m using OCI as my backup for cloud services and as sandbox to conduct experiments. Their instance comes with full root permission which means you can do whatever you want. Run your personal website with Apache/PHP, backup your data with NextCloud as GoogleDrive alt , start a blog with WordPress. OCI supply all the things, you just need to click the app to deploy.
In conclusion, OCI is a powerful and reliable cloud platform that offers a wide range of services for various use cases. Its Always Free tier is a great way to get started with the cloud or explore new possibilities without any cost or risk. Compared to other cloud providers, OCI stands out for its consistent pricing, performance, security, and customer service. If you are looking for a cloud provider that can meet your current and future needs, you should consider OCI as your choice.
Good luck!
