8 Top Benefits of Public Cloud Every Tester Should Know

Benefits of Public Cloud

While few can deny the prevalence of the public cloud in the IT landscape, some businesses remain hesitant to abandon their on-premises systems, private or hybrid cloud solutions, and go “all in” on the public cloud. If you’re in that camp, you need to understand what you’re missing and why the time has come to embrace the cloud.

The public cloud hosting market provides a variety of deployment models that address the needs of businesses of all sizes and industries. In this article, we will examine the advantages of public cloud.

Benefits of Public Cloud and Best Tool for Cloud Testing

1. Increase Security

Forward-thinking businesses worldwide recognize the added security benefits of moving to the cloud. However, there is the misconception that if you don’t control and house your data, it’s less secure. 

This couldn’t be further from the truth, as evidenced by the fact that on-premises solutions account for the vast majority of data leaks. There are a variety of reasons, why the public cloud is beneficial; including:

  • Expertise in cyber security: Big cloud attracts the world’s most talented engineers and has the resources to fund large security teams and the most advanced security tools. You gain access to highly skilled teams of IT professionals tasked solely with protecting your data in the cloud infrastructure.
  • Security advancements: Cloud-native security services are the most advanced. Security innovation is taking place in the cloud and is being tailored to cloud-based solutions.
  • Regular penetration testing: In Public clouds, regular penetration testing is held to higher standards than on-premises solutions and private clouds. Some private clouds are never subjected to acceptable levels of penetration testing.
  • Access is restricted: The majority of data breaches are the result of human error. Cloud sceptics believe that keeping their data in-house gives them more control, but the opposite is true. For example, data stored in the public cloud has a minuscule chance of falling into the hands of the wrong people as a result of an employee error. Your risk increases as human control over your information decrease.

2. Global Availability

One of the main benefits of the public cloud is, a fast and inexpensive way to store data in any country on the planet.

For example, if a company wants to reduce latency for its services, it has to choose a provider that stores the cloud in its preferred country. 

This can also be used to keep data in a specific jurisdiction. SIM-Cloud, for example, is housed in a data center in Germany, where the law protects against illegal seizures.

Owning a data center of your own outside of your home country is a challenging and expensive endeavour. The business will also need to determine the specifics of the nation’s legislative structure in addition to the logistical issue. 

For example, your company won’t have to deal with this problem any longer if you use a cloud solution because the provider has already taken care of everything.

3. High Scalability

The public cloud can be scaled without investing in new hardware and manually installing it in an on-premises data center. The virtual machines can have additional CPU cores, RAM, or storage whenever you need it. The hardware foundation of the cloud is kept in the provider’s data center, and the resources are also made available via remote access.

Small businesses that are unable to expand their IT capabilities by purchasing expensive hardware will find this benefit of public clouds to be especially helpful. 

The public cloud can be instantly scaled to fit the task at hand and expanded as the business grows. Compared to a dedicated server, this is much faster and more affordable. You will need to purchase new components and swap out the old ones if you need to scale a physical server.

4. Provider Takes Care of Maintenance

You no longer need to purchase hardware or software when you rent a cloud; this is now the responsibility of your public cloud provider. The provider is also in charge of all elements required for the infrastructure to operate, including power, redundant components, security, cooling systems, etc. So with the Public cloud, your company saves time and money by doing it this way.

This benefit of using a public cloud also applies to renting dedicated servers. However, there will be more maintenance expenses if the business deploys its infrastructure on-site. Rent a public cloud if you want to free your company from these costs while still enjoying all the advantages of the public cloud.

5. Save Money

What are the financial savings possible with the public cloud?

Naturally, it depends.

Some businesses actually save millions of dollars, but if your account needs to be managed better, you might not even see cost savings.

But you can get an idea of how much you can save if you look at why the public cloud saves you money and then look at your own IT environment. You save money by using the public cloud because you have the following:

No investments in capital: Equipment and storage space doesn’t need to be purchased. Setting up a public cloud subscription is inexpensive, and you only pay for the resources you use after that. Your infrastructure spending will change from a capital expense (CapEx) to an operating expense thanks to a public cloud.

There are no upkeep or update expenses: Maintenance is handled by your service provider and is a fixed expense covered by your subscription. In addition, your service provider manages all software updates and includes them in your hosting package, so you or your staff are not required to carry out upgrades.

Pay-per-use billing: You only pay for what you use, which prevents the idling of resources and unnecessary spending. Additionally, you have the freedom to quickly scale up or down, using more computing power when necessary and less when not.

Less expensive energy: By not having internal servers, you save money on the energy they use to run.

6. High Stability

Architecturally, the cloud is a fault-tolerant solution. The virtual machine will use the processing power of another server if a component malfunctions. 

The systems will continue to run, and cloud services will continue functioning as usual. Reliable service providers also make use of redundant cloud components. This significantly reduces the possibility of catastrophic failures.

Zones of availability may be used to increase fault tolerance. An availability zone is a separate area of the cloud that makes use of the following:

  • Network Connections
  • Independent Computing Instances

A business can double the stability of its services by spreading out the deployment of its systems across two availability zones.

7. Short-Term Investment

Predicting long-term computing power requirements is frequently challenging when a business is still in its infancy. Avoiding solutions that require significant financial outlays, such as on-premises deployment or long-term leasing of another infrastructural solution, is advised in such circumstances.

This problem is resolved by the public cloud’s pricing structure, which allows clients to only pay for resources that are actually being used. By doing this, the client’s business can utilize a scalable and effective computing platform without entering into long-term contracts or investments.

8. Server Redundancy

Private clouds are frequently single-tenant, so your entire company is impacted if the server crashes. Additionally, you are responsible for putting redundancy measures like backup servers and cloud disaster recovery plans in place with on-premise infrastructure.

However, because public clouds support multiple tenants, your resources are dispersed among several servers. Therefore, your applications can automatically switch to another cloud server if one goes down. Your applications and data are always accessible, thanks to it. By doing this, you can lessen downtime and maintain the efficiency of your company.

Overall, public clouds have several advantages over private clouds and on-premise infrastructures. First, they are usually less expensive, easier to maintain, and more secure. 

Furthermore, public clouds offer scalability and redundancy, which are difficult to achieve with on-premise infrastructures. So, if you’re considering moving to the cloud, a public cloud might be the best option for your company.
