A beginner’s guide to cloud computing
A very basic definition of cloud computing is the provision of computing services over the Internet. Computing services may include servers, databases, software, analytics, storage, networks and information. The cloud makes it possible to deliver these services quickly, reliably and affordably. Below are definitions and examples for a brief guide to cloud computing.
Definition of Cloud Computing
Cloud describes a network of computers, operating programs and applications. Known as virtual hosting solutions, they run on connected servers instead of a local machine. Software, processing power and data storage are provided remotely. All cloud computing information files and application programs remain secure in remote data centers.
Sharing and collaboration can be done seamlessly and effortlessly, regardless of location or user device.
Types of Cloud Computing
To start this cloud computing guide, we need to mention the different types. Many different cloud computing models exist and meet the diverse needs of different businesses. Certainly, over the years, various models, types and services have evolved in cloud computing. So, determine your cloud computing architecture to enjoy optimal cloud services.
The public cloud is owned by third-party cloud service providers. They also own the resources, such as hardware, software, and supporting infrastructure. In addition, these services can be accessed and managed through the web browser. The public cloud follows the multi-tenant architecture supported by the pay-as-you-go model.
The private cloud offers a series of cloud computing resources. They are exclusively used by a company or an organization. The cloud may be located in a user’s on-premises data center. In addition, a private network manages and maintains services and infrastructure. Only the user can directly access and control the underlying cloud infrastructure.
A hybrid cloud is a combination of public and private cloud services. Data moves between the two clouds as needed. A key aspect of this solution is its greater flexibility and broader deployment options. It also optimizes the user’s existing infrastructure and security. It also ensures full compliance.
Types of services offered by cloud computing
IaaS [Infrastructure as a Service]
IaaS or Infrastructure as a Service is provisioned and managed over the internet. Moreover, users resize it as needed. You can realize significant savings on the investment related to the purchase and management of physical servers and other infrastructure. The cloud computing service provider manages the infrastructure, the software system and the middleware of the operating system, as well as the applications. Plus, you only pay the rent to use the service component you need.
PaaS [Platform as a Service]
PaaS provides a development and deployment environment in the cloud. Resources can be purchased on a pay-as-you-go model. Indeed, this service includes IaaS, middleware, Business Intelligence services, database management solutions and deployment tools. You don’t have to invest in expensive software licenses. When you subscribe to PaaS, the cloud service provider handles everything.
SaaS [Software as a Service]
SaaS offers a complete software solution on a pay-as-you-go basis. Users can log into the system and access cloud-based applications through the Internet. The vendor also offers SLAs or Service Level Agreements to enable access to leased software and hardware.
Serverless computing is a blueprint in which developers build applications faster. They don’t have to worry about managing the underlying infrastructure. In addition, the tasks associated with the provisioning and management of the infrastructure are the responsibility of the provider.
Benefits of using cloud computing
Cloud computing and its various deployment models have streamlined or eliminated many common business problems.
- Businesses don’t need to invest in high-capacity servers or equipment rooms. They can manually store and back up data on hard drives and external devices.
- They don’t need to hire expensive in-house experts to manage and troubleshoot server systems.
- The vendor or vendor handles all backups, maintenance, and troubleshooting.
- Access to resources is not affected by users’ geographic location.
- You do not need to force, but the original software systems and keep manually updating the latest versions. Cloud-based software customizes to meet user needs.
- With cloud computing, your data remains completely secure and protected at all times. There is no risk of losing crucial business data, even during major disasters.
- Sharing and working on cloud-based files is the best way to achieve perfect coordination between remote workers and teams.
- Cloud computing saves you money because you don’t need to buy expensive software or hardware systems. If done by the vendor, you also potentially save on IT expert salaries for installation, maintenance, and troubleshooting.
Anyone using the Internet will probably already be using cloud computing in some ways. We use the system when we send e-mails, visit multimedia platforms, store files or play online video games. Cloud computing has many other great uses. These include
- Data storage, backup and recovery
- Build, test, and build apps
- Data analysis
- Content creation for social media and other entertainment platforms
- Mobile banking
- Customer relationship management
- Inventory management and logistics
Cloud Computing Misconceptions
In our guide to cloud computing, we want to mention the many technical and economic benefits provided by cloud computing, but there are still trust issues with the acceptance and implementation of the technology. People keep some misconceptions associated with cloud computing.
Certainly, the cloud provider can have access to all the data.
Reality: All information stored in the cloud remains fully encrypted. They are also encrypted while in transit. No one can access or decode the data.
The cloud takes away control of your data and processes.
Reality: Cloud services can be used on a pay-as-you-go basis. Thus, you can adapt the use according to your needs. Migrating data to and from the cloud is also quick and easy. You can download the information whenever you need it.
Cloud solutions are risky because they are prone to security breaches.
Reality: Quite the opposite. Security improves once data is migrated to the cloud. A two-factor authentication method is used to verify user identity and improve security. Security vulnerabilities are usually due to human error.
Moving to the cloud can cost you time and money.
Fact: Cloud migration happens quickly and is also cost effective. You don’t need the assistance of IT experts during and after the migration.
This is a technology that is here to stay for a long time, so this is just a brief guide to cloud computing. Indeed, you can reap the full range of benefits if you follow best practices for leveraging cloud services. But your cloud computing experience will depend on the reputation and efficiency of the cloud service provider you use. So be sure to do your research thoroughly and choose the best cloud service provider to get the most out of your investment.
