Cloud computing is the provision of computing services such as server, storage, database, network, software, data analytics over the internet to provide fast innovation, flexible resource and affordable budget services. In cloud computing, you usually pay for the cloud service you use, which allows you to lower your operating costs, use your infrastructure more efficiently and work flexibly based on your business needs.
Its institutions and companies focus on cloud computing and the reasons for this;
Low Cost: With cloud computing, you do not have to host servers and software within your company. Thus, investments on server racks, power, cooling, and IT experts managing these infrastructures are eliminated.
Fast: Most cloud computing services are provided on self-service and on demand, so even large amounts of computing resources can be delivered much faster, so businesses can work flexibly without having to make a capacity plan.
Global: Cloud computing has flexible scaling capability so that the right amount of IT resources (such as storage, bandwidth) is provided at the right time and geography.
Efficient: Companies need a large number of shelves and stacking in the data centers they host. However, thanks to cloud computing, IT teams are provided to achieve more important business goals by minimizing their hardware and software needs.
Performance: Cloud computing services operate on secure data center networks around the world, upgraded to efficient computing hardware with the latest technologies. Thus, it enables applications to experience less network latency and is much more advantageous compared to corporate data centers.
Reliability: Since data in cloud computing is available from multiple redundant sites in the cloud provider's network, data backup, disaster recovery and business continuity services are offered easier and cheaper.
Security: Cloud providers offer a wide variety of policies, technologies and controls to protect companies' data, applications and infrastructures from potential threats.
Some of the Services Provided by the Cloud Provider
- Quickly build, deploy, and scale cloud-specific applications such as web, mobile, and API
- Data storage, backup, recovery
- Audio and video streaming
- Providing the latest versions and updates of optional software known as Saas
- Developing and testing applications at low cost
- Providing artificial intelligence and machine learning services by combining data in the cloud system
- Presenting smart models to extract meaningful information from big data
Cloud Service Types
Most cloud computing services fall into four main categories;
Infrastructure as a Service (IaaS): Servers and virtual machines that make up the information technology infrastructure are rented from a cloud provider on the basis of payment as much as you use storage systems, networks, operating systems.
Platform as a Service (PaaS): A cloud computing service that provides an environment for developing, testing, deploying and managing software applications. PaaS is designed to make it easy for developers to quickly build web or mobile applications without worrying about building or managing the infrastructure, servers, storage, networks and databases needed for development.
Serverless Computing: Provides application functionality without constantly spending time managing servers and the infrastructure required for this. The cloud provider handles installation, capacity planning and server management for you.
Software as a Service (SaaS): It is a method of distributing software applications on the basis of subscription on demand. With SaaS, cloud providers host and manage the software application and basic infrastructure and perform all maintenance operations such as software updates and security. Users usually connect to the application over the Internet with a web browser on their phones, tablets or PCs.
