In-house email server VS Cloud-based service
There comes a time when every business has to make a decision on whether they will use an in-house server or a cloud-based one. Nowadays it is hard to decide, because information technology is developing rapidly. An in-house server is better in some aspects, but the cloud-based one has its advantages too.
What is Cloud? (Cloud computing)
Some years ago only large enterprises stored their data in the cloud. In such cases data is stored on the cloud provider’s server instead of hardware. Users can access these devices via the Internet. There are numerous ways to classify the Cloud computing services, like the type, the accessibility or the price.
There are free cloud storages, probably most of the businesses used these ones. The most popular is Google Drive which provides 15 gigabytes of free storage space, or Dropbox which offers only 2 gigabytes. There are a lot of other free cloud storage services, but all in all, the provided free storage always seems to be deficient for a company. Of course, we can augment this capacity as long as we can afford. But let’s compare the in-house server and the cloud-based service. In the following picture, we summarized the pros and cons of these two solutions.
To sum up it is cheaper to use a cloud-based service for a company. Due to the continuous improvement, the services can be customized for business’s needs more and more, and with the innovations, they try to entirely satisfy the customers’ demands.
With Infrastructure as a service (IaaS) we use a virtual server to store our data. We can create different networks inside the server.
With Software as a service we use the software online, we don’t have to install it and we don’t have to deal with updates. If an error occurs with the computer, the data will not be lost.
With Platform as a service, they provide a cloud-based platform to operate the application. So the software comes from the provider. The biggest advantage is that we can deploy applications directly into the cloud in minutes.
Public cloud: The provider uses its own resources to satisfy the customers’ server needs. We only have to pay for what we use.
Private cloud: Only the customer can manage the infrastructure. The hardware and the software are owned by the customer.
Hybrid cloud: The combination of the previous ones; the public cloud completed with the private one.
Community cloud: share the resources among specified servers.
Whether we choose the in-house email server or the cloud-based service we have to consider a lot of factors. If we select the appropriate informatics infrastructure we can save a lot of expenses. The hybrid systems, which operate based on cloud computing and operate with private servers as well, can be a solution if we can’t make the decision. They are able to determine if a data has to be managed on the cloud or private server. Using a hybrid cloud is becoming more and more popular among business, and analysts forecast a big growth for the following years, but it is likely that it will have some competitors on this market…
