The world of computing is changing. The days of private data centers are waning, and with them the benefits they offer to business owners.
Private cloud computing offers a more secure environment, but it doesn’t have the same scalability as public clouds do. Regardless, many businesses in 2021 are resorting to these solutions to enhance their business.
This article will discuss how these two different types of cloud computing compare. This will relate to them in terms of cost, security, and overall functionality.
So whenever you’re ready to involve yourself in the battle between private cloud vs public cloud, keep reading.
Public Cloud: What Is It?
A public cloud is a data center that offers all the resources of its servers to the general public.
Public clouds are often used in conjunction with virtualization technologies. This allows for efficient use of hardware and ease of management throughout an organization’s network.
This type of computing is popular due to rising concerns about security within private networks. It also has to do with issues related to performance degradation on large machines.
Moreover, public cloud computing is also attractive. It allows for scalability in the event that an organization has long-term growth or unexpected increases in users.
On the negative side, there are concerns about security when utilizing public clouds. Some organizations worry about losing control over their data. The lack of dedicated hardware can be a problem as well.
If something goes wrong with one of these virtual servers, other companies could have performance problems on account of it.
The Pros & Cons
The benefit here is that companies can tap into vast amounts of raw processing power. They do so without having to maintain their own equipment or invest capital in infrastructure upgrades.
Furthermore, cloud computing can help companies scale their business, as needed. If the company experiences a spike in growth or an unexpected surge of users for any reason, it’s much easier to expand resources on public clouds than preexisting private ones.
On top of that, because these machines are shared hardware and not dedicated servers, there is more security. Security against threats like DDoS attacks (a type of cyber-attack).
These types of actions tend to be focused on one machine specifically. Many virtualized servers run on one physical computer platform instead of individual machines. Thus, they’re less likely to fall prey to such issues.
The downside? Public clouds tend to be more expensive than private ones. This is because they’re open 24/365, whereas most businesses run outages during off-hours when there aren’t as many users on the network. The negative connotation of using public clouds is the loss of control over data.
Many companies are hesitant to use these servers because they may not be able to delete their information if they want. Some worry about how secure it actually is when third parties have access.
Private Cloud: What Is It?
A private cloud is a data center that focuses on the needs of one organization.
Private clouds are built around virtualization. They’re contained within an organization’s own network.
These types of networks offer more security than public ones. This is because there aren’t as many external threats to worry about. However, their scalability isn’t nearly as good.
The hardware is also dedicated. So if there’s a problem with one server it doesn’t affect others in the network. This is a big advantage over public clouds, which have to share resources.
The Pros & Cons
The benefit here is that companies can be certain that no outside threats will compromise sensitive information. They won’t require constant updating and maintenance to keep them at peak performance levels.
They also have complete control over how much bandwidth each department gets. This is something extremely important for businesses with high resource-intensive applications. For instance, such as engineering firms and media production houses.
The downside private clouds tend to be more expensive to implement. They are less flexible because of the lack of scalability. This is not a problem for most businesses but can be an issue if you’re expecting to expand in the near future.
Furthermore, because they’re contained within an organization’s network, private clouds aren’t as secure. They also suffer from many of the same issues public ones do in that there is no guarantee that all data will be deleted if requested.
Many businesses still take advantage of both cloud computing options depending on what needs are being met at a particular time. The key here is knowing how much risk you can afford and what your business requirements are. This is done before making your final decision about which one works best for you!
How Are the Two Similar?
Both private and public clouds are built on virtualization. The idea of using software to run multiple servers as if they were one machine.
This makes it much easier for companies to scale their business, especially in terms of cost-effectiveness. This is true when compared with traditional data centers that have fixed amounts of hardware.
Moreover, both types allow businesses to pay only for what services they use. This applies rather than having expensive server rooms sit idle or just barely being used half the time. Cloud computing is a great way for organizations big and small alike to reduce overhead costs without sacrificing speed.
The biggest similarity between them is how easy it can be to change infrastructure depending on your needs at any given time. Whether you need more storage space or less power, virtualization allows you to do this easily and quickly.
The difference between public vs private cloud is that the former kind is outside your network with its own hardware. While the latter can be run by either yourself or a third party but remain within your organization’s boundaries at all times.
Which Is Best for You?
The best kind of cloud computing will depend on your business needs. Do you want to save money but don’t mind sacrificing some flexibility? Then a private cloud might work out perfectly for you!
On the other hand, do you need everything at your fingertips quickly and with no downtime regardless of cost? The public option is probably better suited to satisfy these requirements.
It’s important to remember that there are also hybrid options available if neither one ends up working out too well by itself. It all depends on what works best for your organization as a whole!
Not to mention, both private and public clouds can be great for businesses that want to expand. Especially those that want to avoid the additional stress of worrying about how they’re going to maintain technology.
However, private clouds tend to be more reliable and secure. This is because they’re contained within your organization’s network. This is why many businesses use both private and public cloud computing as situations call for different solutions!
How Are They Different?
The biggest difference between the two types of clouds has to do with where their infrastructure resides – namely, whether it stays on-premise or gets hosted elsewhere over the internet.
The former means that its servers are located in your own data center (or somewhere else under your control), while the latter means that you’ll have complete access to virtual machines from anywhere at any time provided there is an active connection.
A big thing to keep in mind here is flexibility. You need near-total freedom when accessing a public cloud for any kind of project, even if it only lasts a short time.
The biggest difference between the two is that public clouds are typically much less secure due to their remote nature – after all, anyone with an internet connection can access your servers from anywhere in the world!
However, private ones don’t have this issue since they’re kept within your organization at all times and you decide who has access when. In addition, there’s no risk of downtime or data loss either because everything stays on-premise unless you request otherwise (e.g., moving things back and forth manually).
On one hand, not having full control over where hosted VMs reside could be frustrating; while some companies use both options depending on the project, others might not have access to a public cloud at all due to various reasons. In addition, it could be expensive depending on the specific service you’re using – some of them can get rather pricey after a while even if they are being used for short periods!
