Cloud Computing. Theory and Practice

Cloud computing is a model for delivering computing resources over the Internet. This means that users can access their applications, data, and computing resources from any device with Internet access.

The market for cloud technology is growing rapidly, attracting the attention of both large corporations and small businesses. Estimates for this market are very optimistic. According to Gartner Inc., worldwide spending on public cloud services will grow 20.7% to $591.8 billion in 2023, up from $490.3 billion in 2022. This is higher than the 18.8% growth forecast for 2022. One of the reasons for this growth is the increasing number of consumers using cloud technologies for work and data storage. We also expect the development of new technologies and services in this area, such as quantum computing and machine learning, which will lead to even greater market growth.

One of the key benefits of cloud technologies is their flexibility. Companies can easily scale their computing resources as needed without having to buy new hardware or hire additional staff to maintain it. In addition, cloud technologies allow you to automate routine tasks.

A clear example of the successful use of cloud technologies is Airbnb, which uses Amazon Web Services to scale its infrastructure and provide high-quality customer service. Cloud technologies have allowed Airbnb to scale easily its computing resources to manage massive amounts of data.

Many major global brands are using cloud technologies to meet their business needs:

• Coca-Cola - to increase the efficiency of its business processes.
• BMW - to develop and test new products and services, and to improve the performance and safety of its cars.
• Adobe - to process and store large volumes of data used in the development of its software products.
• GE Healthcare - to create digital data management platforms that help physicians and healthcare organizations improve healthcare quality and outcomes.
• UPS - to optimize its logistics and transportation processes and improve the efficiency of its package tracking systems.

ChatGPT is very popular now. This chat bot has become the fastest growing IT product in the history of the IT market. Chat reached 100 million monthly active users in January 2023, just two months after its launch. This incredible success was made possible in part by integrating with cloud technologies.

Types of Cloud Services

There are different types and models of cloud technologies, each with its own advantages and disadvantages, depending on a number of factors: service delivery model, level of availability, types of data processed in the cloud, etc. There are three major types of clouds.

Public cloud

The public cloud is the most common type of cloud technology. It provides computing power and services in a publicly accessible way over the Internet, allowing users significantly reduce the cost of infrastructure and its management. Widely used for business applications, data storage, and other enterprise tasks, public clouds offer high levels of availability and scalability. Learn more about the advantages and disadvantages of public cloud in our article.

Private Cloud

A private cloud is used exclusively by an organization and managed by its IT department. It can be physically dedicated hardware within the organization or a cloud managed by an external provider. A private cloud provides the highest level of security and data control, but requires a significant investment in infrastructure. To learn more about what a private cloud is and how it is used, read our blog.

Hybrid Cloud

A hybrid cloud is a combination of public and private clouds. For example, a customer can use public cloud services for non-sensitive data and a private cloud with a higher level of security for more important data. This model allows organizations to reduce infrastructure and management costs while maintaining control over critical data.

Basic Cloud Services Models

IaaS (Infrastructure as a Service)

Infrastructure as a Service is a model for providing access to cloud infrastructure: virtual servers, data storage, and network resources. Customers can use this infrastructure to deploy and manage their own applications and services. The largest and most prominent IaaS providers: Amazon Web Services, Microsoft Azure, and Google Cloud.

PaaS (Platform as a Service)

Platform as a Service is a model that provides customers with a platform to develop, test, and deploy applications without having to purchase and maintain their own infrastructure. PaaS includes tools for application development, database, analytics, and testing. Examples of PaaS providers: Heroku, Google App Engine, Salesforce.

SaaS (Software as a Service)

Software as a service is a model that provides access to software over the Internet. Instead of installing applications on their own servers, customers can use applications in the cloud provided by SaaS providers. Examples of SaaS applications include Dropbox, Microsoft Office 365, Salesforce CRM, etc.

Key Benefits of Clouds

One of the key benefits of cloud technologies is scalability. Businesses can quickly scale their cloud resources up or down as needed. This means that companies do not have to buy additional equipment to expand their infrastructure. In this SIM-Cloud example video, we demonstrate how easy it is to scale by simply adding an instance to your cloud.

Another key benefit is accessibility. Companies can access their data and applications from anywhere in the world with an Internet connection. This is especially important for companies with offices in different cities or countries that need to collaborate quickly and conveniently.

Cost. Companies can save money on the hardware and software they need to store and process data. They can use the services of cloud providers on an as-needed basis, reducing costs.

Flexibility and ability to respond quickly to market changes. Businesses can rapidly deploy new applications and services, manage business processes, and collaborate in real time.

However, perhaps the most important benefit is security. Businesses can store their data in the cloud, where it is protected from loss, damage, and cyber-attacks.

How Businesses Use Cloud Platforms

Today, cloud technologies have become an integral part of business processes, allowing companies to save time and money, increase work efficiency, and provide better data protection. Here are the top 5 business benefits:

1. General Access
Cloud services such as Google Drive, Dropbox, OneDrive allow users to store and share files from anywhere in the world, regardless of location or device. Using such a service makes it easier for employees to collaborate and increases productivity by keeping all the files they need at their fingertips. This is especially useful for companies with a decentralized structure. Here you can see the demonstration solution for the IT infrastructure of the pharmacy network.

2. Stable Access

3. Big Data Analysis and Processing
Cloud services allow companies to analyze large amounts of data and gain valuable information about their customers, products and the market in general. As a result, companies can make reasonable decisions and increase the efficiency of their business.

4. Business Process Automation and Project Management
Businesses can use cloud services to collaborate on projects, share documents and manage tasks. This allows employees to be more efficient and organized, increasing productivity and reducing the time it takes to complete tasks.

5. Data Storage and Protection
Cloud providers can provide various methods of data protection, such as encryption, identity and access management, multi-layered protection against malware and DDoS attacks, and data integrity and availability controls. In general, the use of cloud hosting can improve the security and reliability of data storage and processing. Here is a prime example of how IT modernization can provide a significant competitive advantage in real estate.

Choosing a Cloud Solution

The cloud is the software and infrastructure that supports its operation and offers a number of benefits specific to that technology. There are varieties of technologies that can be used to build cloud infrastructures.

It is important to note that the choice of a particular technology should be carefully considered and based on an analysis of business needs, budget, scalability, and other factors. This will help organizations effectively leverage the capabilities of cloud technologies and achieve their strategic goals.

Choosing a cloud solution can be difficult and often error-prone. Many customers choose popular solutions without a proper understanding of what exactly they need for their business.
