Thanks to them, you can be sure that your sensitive information will be safe and sound. Finally, cloud services work best for companies with growing bandwidth demands. If your requirements change, you can increase cloud capacity at any time. The choice of the best option depends on many factors, including the size and complexity of your business, and the requirements you’re going to cover with a cloud solution. SaaS SaaS (Software-as-a-Service) means delivery of ready software products via the Internet on a subscription basis. This is the simplest option to maintain. Besides, using SaaS solutions is a good choice for startups and small companies with limited resources. The key benefits of the Software-as-a-Service cloud computing model are time-saving, accessibility, and off-the-shelf solutions that you can easily set up and use. When it comes to downsides of SaaS, you may face a lack of integration or performance issues. PaaS PaaS (Platform-as-a-Service) gives users access to a cloud environment for creating custom apps. In this regard, this model is distinct from SaaS offering ready products. By choosing this option, companies free themselves from building and maintaining the infrastructure their applications need. If you are a medium or large company with enough resources, consider trying the PaaS model. Thus, you will get a customized solution that can be easily integrated with other tools and services used within your organization. Clear advantages of this option include easy maintenance, reduced development time, and a quick launch of your products. However, you should take into account the following drawbacks of the Platform-as-a-Service solutions as sudden changes from the vendor, possible runtime issues, and the lack of customization for legacy systems. IaaS The last cloud computing model is IaaS (Infrastructure-as-a-Service). This is self-service that enables users to access and monitor hardware including specialized processors, storage space, visualization services. Relatively large companies definitely should consider using IaaS solutions.
