It’s mentioned that the private cloud doesn’t offer any of the advantages. I Understand it does not provide the durability and elasticity of the cloud, as you are limited to your specified amount of paid-for servers. But it’s still in the cloud, so doesn’t it still keep some advantages? If not, what is the point of it? If you are worried about security, store your data on-premise.
Its not that the private cloud doesn’t offer advantages over using a hybrid solution, or going full cloud with AWS, Azure, etc. The main advantages of using cloud computing at the scale of AWS is difficult for any company to achieve. You could create your own private cloud that has similar services & features as AWS. However, you would have to account for the below advantages of using cloud computing services offered by AWS, Azure, Google Cloud:
• Trade capital expense for variable expense – Instead of having to invest heavily in data centers and servers before you know how you’re going to use them, you can pay only when you consume computing resources, and pay only for how much you consume.
• Benefit from massive economies of scale – By using cloud computing, you can achieve a lower variable cost than you can get on your own. Because usage from hundreds of thousands of customers is aggregated in the cloud, providers such as AWS can achieve higher economies of scale, which translates into lower pay as-you-go prices.
• Stop guessing capacity – Eliminate guessing on your infrastructure capacity needs. When you make a capacity decision prior to deploying an application, you often end up either sitting on expensive idle resources or dealing with limited capacity. With cloud computing, these problems go away. You can access as much or as little capacity as you need, and scale up and down as required with only a few minutes’ notice.
• Increase speed and agility – In a cloud computing environment, new IT resources are only a click away, which means that you reduce the time to make those resources available to your developers from weeks to just minutes. This results in a dramatic increase in agility for the organization, since the cost and time it takes to experiment and develop is significantly lower.
• Stop spending money running and maintaining data centers – Focus on projects that differentiate your business, not the infrastructure. Cloud computing lets you focus on your own customers, rather than on the heavy lifting of racking, stacking, and powering servers.
• Go global in minutes – Easily deploy your application in multiple regions around the world with just a few clicks. This means you can provide lower latency and a better experience for your customers at minimal cost.
