Many CTOs and programmers today are opting for cloud solutions. This solution saves time and, in many cases, can offer substantial cost savings. It often requires knowledge specific to the cloud provider employed. The great strength of these solutions is the elasticity of the resources used. In fact, it's possible to easily increase or reduce the resources used and pay per use. This makes it possible to adapt quickly to an increase or decrease in the resources required to meet user needs.

VPSs are often confused with cloud solutions, as they often use the same key words - "cloud" and "nuagic" - in their marketing approach. Often less expensive than a true cloud solution, VPSs are actually virtual environments running on a standard server. In some cases, the line is very thin, and many features usually reserved for cloud environments can be found in VPSs. This is the case with DigitalOcean, a very popular VPS provider with an increasing number of cloud-like functions. Dedicated backup copy, load balancer, DNS management and more. VPSs are the equivalent of a dedicated server in use, but it's actually a reserved area within a larger server. Often, your RAM is dedicated, but the CPU cores are shared with the users of the server where the VPS resides. VPSs on the same machine share resources, but the machine has sufficient resources to host multiple virtual machines.

This approach is relatively new, and requires specific knowledge of the tools provided by one of the major cloud hosting providers, such as Amazon AWS or Microsoft Azure. Your application is developed directly in a cloud environment, using the tools provided by the provider. To take the example of Amazon AWS tools, it is possible to build a complete application using Amazon's various cloud products. Using products such as Amazon Cognition, S3, API Gateway, DynamoDB, AWS lambda, SES, and SAM/Cloud Formation. Each of the tools provided has a specific purpose. Cognition for user management S3 for static files, such as images, CSS, JavaScript, logs and backup copies DynamoDB for the API Gateway database to expose your scripts or resources AWS lambda for application functionality SES for e-mail SNS for publications and event subscriptions (pub/sub notifications) CloudFormation to build and maintain the entire serveless organization. A small SaaS application that strictly uses a serverless architecture can be developed quickly if the person building it is familiar with the tools he or she is using. Otherwise, the learning curve can be tedious, as it involves many different services, proprietary to the cloud provider, that have to fit together. The serverless approach has a number of advantages. Firstly, it theoretically allows infinite demand growth for the application using this approach (scalability). As the infrastructure is 100% in the cloud, with theoretically unlimited resources, it can increase its resource utilization linearly, without having to think too hard about it.

Dedicated servers are physical servers that are purchased or leased. They are still viable even in the cloud era. They may even be less expensive in terms of hosting bills, but they generally need longer set-up times and may require more maintenance. Both types of solution have their advantages and disadvantages. The choice will depend very much on your available resources. This approach lacks the elasticity provided by cloud solutions and is often more time-consuming to set up. However, it is possible to have a lower total bill with dedicated servers than with cloud solutions. It's often the server management time and other headwords associated with dedicated servers that raise the real bill. Many network administrators still advocate this approach.
