Cloud Computing: The What’s and Why’s

Cloud Computing: The What’s and Why’s

Cloud computing is a hot topic these days, and with good reason. The principle of cloud computing isn’t new, however, many companies are gradually beginning to switch to cloud-based services. This highlights the importance of understanding the nuances of cloud computing terminology and its concepts. But, what exactly is cloud computing?

 

What is Cloud Computing?

Cloud computing enables convenient online storage, networking, and communication. From email and word processing to programs and storage, cloud computing gives you the ability to access your files from anywhere with a secure Internet connection.

Why is Cloud Computing Important?

Before cloud computing was a thing, companies used to store all of their data and software on their own hard drives and servers. If you were part of a large organisation, this could take a long time. Today, cloud computing is a much more efficient alternative. In fact, both businesses and individuals benefit from cloud computing.

Most of us use cloud computing on a daily basis. When we post on social media or binge-watch a new Netflix series, we are using cloud services. Apps such as Facebook, Instagram, Netflix, and Gmail, you can access through an internet connection. This is instead of installing directly onto hard drives or devices, as you would do before.

 

What are the Benefits?

Cloud computing nowadays is one of the most efficient ways to store your information. There are many benefits that come with cloud computing services, let’s take a look at some of them:

  • Reduction of IT costs – Moving to the cloud. You can save money by utilising the services of your cloud service provider, rather than purchasing pricey systems and equipment for your organisation.
  • Scalability – Your company can scale up or decrease its operations and storage requirements to suit your demands. This will give you more flexibility as your needs evolve. Instead of obtaining and installing costly upgrades yourself, your cloud computing service provider may take care of it for you. Using the cloud allows you to focus on operating your business instead of worrying about technology.
  • Business continuity – Saving your data in the cloud means that the cloud will back it up and store it in a secure and safe location, regardless of any crisis. Being able to immediately access your data allows you to continue doing business as usual, minimising downtime and lost productivity.
  • Flexible working environments – For example, you can access data when at home, on holiday, or on your way to and from work (providing you have an internet connection). You can connect to your virtual office quickly and easily if you require access to your data while off-site.
  • Automatic updates – Your system will consistently update with the latest technology on a regular basis, depending on your cloud computing service provider. This could involve newer software versions, as well as server and computer processing power increases.

 

 

Types of Cloud Computing…

Some Cloud computing services can be expensive. However, there are many types of cloud computing, so you can choose which one is best for you.

Public Clouds – Public clouds are cloud environments that are often built using IT infrastructure that does not belong to the end user. Amazon Web Services, Google Cloud, IBM Cloud, and Microsoft Azure are some of the most popular public cloud providers.

Private Clouds – Private clouds are cloud environments that are completely dedicated to a single end user or group, and are often run behind that user’s or group’s firewall. When the underlying IT infrastructure is commits to a single client with entirely segregated access, all clouds become private clouds.

Hybrid Clouds – A hybrid cloud is a unified IT system made up of several environments linked through LANs, WANs, VPNs, and APIs. Hybrid cloud characteristics are complex, and the criteria vary depending on who you ask. A hybrid cloud, for example, might need to include:

  • There must be at least one private cloud and one public cloud.
  • At least two private clouds
  • Two or more public clouds
  • At least one public or private cloud connected to a bare-metal or virtual environment

 

Multiclouds – Multiclouds are cloud architectures that combine many cloud services from multiple cloud vendors, whether public or private. Not all Multiclouds are hybrid clouds, and not all hybrid clouds are Multiclouds. When various clouds form into pairs through some type of integration or orchestration, they become hybrid clouds.

What are the Disadvantages?

However, there can also be some down sides to using The Cloud.

  • Risks to Cloud security and data – You may face threats such as data theft and leakage, account hijacking, technology vulnerabilities in shared environments, and denial of service attacks.
  • Cloud downtime – Technical issues like as reboots, network outages, and downtime can occur in the cloud, just as they might in any other IT setup. These occurrences might halt commercial activities and processes, which can be costly to the company.
  • Limited Control – The cloud infrastructure is owned, managed, and monitored by the cloud service provider. You will have very little control over it as a customer. You’ll be able to manage cloud-based applications, data, and services, but you won’t be able to perform important administrative chores like updating and controlling firmware or accessing the server shell.

 

At Inology, we deal with Cloud Computing a lot. We manage lots of different cloud services for our clients, such as the Office 365 backup programme(which is classed as a SaaS – Software as a Service). This makes things much easier for both us and our clients when dealing with large amount of data and files. Take a look at our page here, where we explain The Cloud in a bit more detail, from our perspective.
