The cloud should be thought of not only as a computing platform that consists of many physical servers and uses virtualization technology to create virtual machines with flexible configurations, but also as a set of services that provide fault tolerance, scalability, and compliance and certification. Cloud services allow you to streamline projects by providing a wide range of tools and capabilities that make cloud platforms like AWS attractive to teams working on complex projects.
Cloud infrastructure differs from on-premises infrastructure in one important way. The company places its IT infrastructure and software on servers on its own premises, and the hosting company places it all in its own cloud environment. Yes, a company can order the amount of capacity it needs, scale up or down based on overall usage, user requirements, business growth, and pay as it goes.
A cloud server uses virtual technology to host business applications off-site. There are no capital costs, data can be backed up regularly, and companies only pay for the resources they use. For businesses, planning to expand globally, the cloud is even more attractive because it allows infrastructure to scale with minimal effort.
A flexible cloud server in Germany from SIM-Networks offers companies the opportunity to quickly get started with an OpenStack cloud platform. Scalable cloud hosting gives you the freedom of choice: a managed server where our specialists provide support and optimization, or develop your own IT infrastructure with the ability to easily scale up or down resources as business needs dictate.
There are a number of fundamental differences between on-premises and cloud environments. Which path is right for your business depends entirely on your needs and what you're looking for in a solution. It is worth noting that the confrontation between cloud and on-premises solutions, if it ever existed, is becoming less antagonistic.
Therefore, we offer a list of the most common factors that have the greatest impact on infrastructure placement decisions:
1. Cost
Organizations that deploy software locally on their premises are responsible for the ongoing costs of server hardware, power, and space.
Enterprises using the cloud computing model pay only for the resources they need, with no maintenance and upkeep costs, and the price adjusts based on how much capacity is used.
Nevertheless, when you analyze the pricing model and cost as a factor of choice, you now have several options. To spread the cost of local infrastructure over time, you can use a loan or the generosity of investors. Yes, it is possible to avoid upfront capital costs for IT infrastructure, but you still have to pay the amount and there are always financial risks on the company's side.
2. Deployment
The on-premises environment is called that because it is deployed within the enterprise and the enterprise's IT infrastructure. The organization is responsible for supporting the solution and all processes associated with it. In a cloud computing environment, whether it is a private, public or hybrid cloud, the resources are hosted on the premises of the hosting company.
However, thanks to the popularity of container platforms such as Kubernetes – software for automating deployment, scaling and coordination – they allow for a patterned deployment, in a positive way.
The deployment process is the same for the end user, regardless of whether your infrastructure is built locally or in the cloud. Because of that, the management of many work processes will look the same today. Regardless of how or where the cloud computing environment is deployed, organizations will be able to access these resources at any time.
3. Scaling
It is obvious that at this point the local infrastructure loses its position. It is not so easy to scale up and down; these changes always involve a long process of purchasing and configuring new equipment. With a cloud environment, it is very easy to scale on demand to grow your IT environment and provision resources when additional capacity is needed. Cloud services provide virtually unlimited scalability.
Scalable cloud architecture is made possible by virtualization. Unlike physical machines, which have fixed resources and performance, virtual machines are highly flexible and can be easily scaled up or down. They can be moved to another server or placed on multiple servers simultaneously, and workloads and applications can be migrated to larger virtual machines as needed.
Third-party cloud service providers have all the major hardware and software resources to scale quickly, something that an individual company could not cost-effectively do on its own.
4. Control and Security
In an on-premises environment, an organization stores all of its data and has complete control over what happens to it. Because of the added privacy concerns, companies in highly regulated industries are often reluctant to move to the cloud.
In a cloud computing environment, many companies and vendors are concerned about data ownership. Data and encryption keys reside with your third-party provider. If the unexpected happens and there is downtime, you may not be able to access that data in time.
Security is often a key barrier to adoption cloud computing. Cloud providers offer tighter access controls than most on-premises environments. They maintain their environments and stick to stricter security policies than the professionals who manage the on-premises infrastructure.
5. Regulatory Requirements
Every company in every industry operates under some form of regulatory control. For government agencies, as well as a number of companies whose industry and regulatory documents are strictly regulated, it is very important that data storage clearly meet the requirements of the law. As a result, sometimes the local placement of infrastructure is not even a matter of choice for the organization itself.
Organizations that have adopted a cloud computing model should exercise due diligence and consider key factors when selecting a hosting company. It pays to make sure that the provider not only offers the necessary cloud services, but also meets all regulatory requirements in its field. Choosing a reliable hosting company that adheres to security standards and provides high fault tolerance is critical for data protection and successful business operations.
When choosing a cloud infrastructure provider, you should also consider the SLA. A service level agreement is important to ensure that both parties, the provider and the customer, understand a single standard of service and performance, including accessibility requirements. By entering into such an agreement, the supplier and customer have a clearly documented method of working according to their mutual expectations. An example of such an agreement is the SIM-Networks SLA.
