What Is Cloud Computing? Here is Everything You Need To Know!

Cloud computing has been all the rage for a while now! Even if you are not directly working in the technology industry, chances are you have heard phrases like, “Everything is moving to the cloud!” “Just upload it to the cloud!” “Don’t you have it backed up on the cloud?” amongst many others being casually thrown around. 

The fact is that cloud computing is everywhere! And its demand is only going to increase, which raises a lot of fundamental questions like, “What exactly is the Cloud?” “What does it all include?” “Is my data even safe in the cloud?” “How does the Cloud Work?”, “As a business do I need to invest in the Cloud?”, “Is A Job In The Cloud Even Worth It?” and “Why Is Cloud Computing All The Rage?” If you are even a little bit curious about exploring cloud technology and how you as an individual, enterprise, or professional can benefit from it, this guide is for YOU! 

Let us start with the basics; what exactly is cloud computing? 

Simply put, cloud computing is a term used to describe the internet to provide computing services like storage, servers, databases, networking, software, analytics, and intelligence. This is done to optimize resources, create an agile and dynamic workflow, and provide economies of scale. As a result, cloud technology allows you to cut costs, use resources more flexibly, and allow for more innovation. 

Where Is The Cloud Working From? 

What Is Cloud Computing Here is Everything You Need To Know!

Okay, by now, we know you know that cloud computing operates by leveraging the internet to provide users with various services. However, where exactly is your data being stored ultimately? What infrastructure is helping cloud services operate smoothly? Does the interweb have an address? 

Now we are apologizing in advance for popping your bubble if you thought that your data in the cloud was coming from real clouds formed by a cluster of algorithmic data that pours into your screen after getting heavy from all the information it stores. In actuality, there are physical storage centers known as data centers that store all the information that helps your cloud services to operate smoothly. 

How are cloud data centers different from traditional ones?

Every business needs a data center. This unit stores all the essential information a company needs to access, run and scale its operations. It includes company information, assets, and applications. Traditional data centers are physical storage units with huge hard disks that store a company’s data. These are expensive, require external storage costs, and are time-consuming and complicated to upgrade. In contrast, cloud data centers store your data on the internet, providing you with a more affordable option, making it easier for your business to scale up or scale down, and providing you with the ease to choose your service providers based on your location in quicker access. 

Major cloud services like Google, Amazon, and Microsoft all have their own data centers. These giants are backed with billions of dollars which means many resources are being pumped in to provide you with the highest quality of services. In fact, companies like Google are heavily investing in building more data centers and improving the efficiency of their existing ones. By choosing to opt with a cloud data center, you are also making a more sustainable choice as a business. 

The major cloud giants like Google, Amazon, Microsoft, Oracle, and IBM all offer cloud infrastructure that companies of all sizes can leverage to innovate and provide their unique services without worrying about the overheads or hefty investments in equipment. For example, the popular e-learning platform Khan Academy uses the Google Cloud App Engine to provide e-learning services to over 18 Million+ students each month.

Similarly, Amazon Web Services are used by the ultimate streaming service Netflix and the world’s most famous professional networking platform LinkedIn uses Microsoft Azure. In addition, Microsoft Azure offers their platform to some of the biggest brands in the world, like Samsung and eBay too. Furthermore, companies with cloud data centers are renting out their infrastructure to help enterprises in every part and field of the world provide their services seamlessly. As a result, cloud data centers play a big role in making technological innovations and advancements accessible in today’s world.

Being green always costs a lot of green itself! Thus, making it difficult for small businesses to make eco-friendly choices. However, companies like Google, Microsoft, and Amazon have the resources to make more sustainable choices. By choosing to use cloud data centers and services, you hence choose sustainability and green choices. For instance, Google aims at using 24/7 green and clean energy across all their data centers by 2030. In addition, Microsoft Azure offers a 98% more carbon-efficient footprint than a traditional data center. 

What Are The Different Types Of Cloud Computing? 

There are three main types of cloud computing: private clouds, public clouds, and hybrid clouds. There are also three main types of cloud computing services: Infrastructure-as-a-Service (IaaS), Platforms-as-a-Service (PaaS), and Software-as-a-Service (SaaS), but more on that later! 

Public Clouds: Owned and managed by third-party cloud providers, companies that offer cloud computing resources like servers and storage over the internet. Companies take full responsibility to provide you with and manage the hardware, software, and other infrastructure you need for your cloud services. You can access these services and manage your account from anywhere using a web browser. Google Cloud, Microsoft Azure, Amazon Web Services are a few such examples of public cloud services.

Private Cloud: As the name suggests, this is a private network belonging to a single business/entity. This cloud is physically located on the company’s on-site data center. Its services and infrastructure are owned, managed, and maintained by the business itself. Companies can also host their private networks through third-party service providers.

Hybrid cloud: An amalgamation of public and private clouds, cloud services that fuse technology to share data, and application transfer between private and public clouds. A hybrid cloud offers great flexibility, more deployment options and helps in powering up your existing infrastructure, security, and compliance. 

A Cloud Comparison: Not all cloud requirements require the same type of cloud computing. The cloud architecture you choose to deploy your services on will differ based on your individual or enterprise requirements. One needs to consider three different factors before choosing to deploy cloud services: on a public cloud, private cloud, or hybrid cloud.

What Are The Different Types Of Cloud Computing Services? 

Now that we have covered the cloud architecture used to deploy your services, let us move onto the services themselves! Cloud computing can be divided into three major categories: infrastructure as a service (IaaS), platform as a service (PaaS), and software as a service (SaaS). These are often clubbed together as a cloud servicing stack as they build on top of one another. Being aware of what they are and how they differ can help you structure your business better! 

SaaS: Software as a Service

These are cloud application services that are made available to users through the internet. They are managed by third-party vendors and are made available typically on a subscription basis. With SaaS, cloud providers host and manage the software application and underlying infrastructure and handle any maintenance, like software upgrades and security patching. Users can connect to this software using a web browser or an application available to them via their phones and other computing devices. This takes away the hassle of figuring out how cloud computing works; one can simply focus on choosing the software that directly fits their needs. 

IaaS: Infrastructure as a Service

In this model, the most basic service offered in cloud computing is the server, storage, and network resources delivered to the subscribers via the internet. This infrastructure allows organizations to adapt to cloud computing, resulting in faster and more efficient workflows. IaaS providers also enable users with a variety of other services such as: 

  • Detailed billing
  • Log Access
  • Security
  • Clustering
  • Storage Resilience (like providing with backups)
  • Load Balancing
  • Monitoring

PaaS: Platform as a Service 

This cloud computing model provides customers with a complete cloud platform from the hardware to the software and infrastructure. As a result, users can develop, run and manage applications without having to bear the cost and inflexibility of hosting them on-premise. This model usually works on a membership model. Users can pick a plan that suits their requirements in terms of uses and frequencies. All major cloud service providers like Google, Microsoft Azure, and Amazon Web Services offer their platform as a service.

How Safe Is Cloud Computing? 

Cloud computing uses the internet to make your data, systems, and applications accessible to you. However, having your information on servers that are not entirely under your control may cause you to question its safety standards. 

It is natural to wonder if your data is secure when it is stored in the cloud infrastructure. Here is the kicker, though: The data that you save with cloud service providers is probably safer than the data stored on your computer’s hard drive. Viruses and malware can infiltrate data on your physical servers. The security measures taken by large cloud service providers are likely to be more powerful and robust than what you have on your personal devices. 

How is data protected in the cloud? 

There are a bunch of security measures that are taken to prevent your data from any misuse. For starters, the servers are located in warehouses that very limited workers have access to. The files are also encrypted, making it difficult for cybercriminals to access. 

Here is how you can be assured that cloud computing is a secured space for storing your data: 

  1. Frequent Security Updates: While we as individuals may be guilty of frequently hitting snooze on our safety updates, the world of computer security is very different. Cloud companies that overlook your cloud servers consistently update their security measures to ensure that your data is protected. 
  2. Built-In Firewalls: Cloud providers have built-in firewalls that protect your data. This firewall can be hardware or software-based and acts as a barrier that filters out suspicious and unwanted traffic. This makes it difficult for hackers to slip viruses past you. 
  3. Third-Party Testing: Cloud service providers usually encourage third-party testers to hack and find weaknesses in their current systems. This way, they ensure that they are regularly working on and protecting themselves from hackers. Giant cloud service providers even have programs like the Google Vulnerability program that offers these ethical hackers a bounty prize ranging between 100 USD- 30,000 USD to find bugs in their processes. 
  4. Auto Patching and AI: Cloud providers use AI to protect your data. They use built-in algorithms to find and identify any vulnerabilities in their existing security measures. Thus enabling them to carry out safety checks regularly.
  5. Ultra-Backed-Up Data: One of the biggest issues with storing your data on a physical hard disk is the risk of losing it to a natural cause. What do you do if there is a power outage or if someone spills water all over your hard disk? With cloud storage, your data is always backed up; in fact, they back up your data several times over. That way, you can access it from a backup server if anything goes wrong. 

How can you, as a user, ensure that your data is safe? 

Here are a few ways that you can enhance your safety while using the cloud:

  1. Data Encryption: Make sure that you use a cloud service provider that encrypts your data. This way, it is more difficult for hackers to get your information since it is all scrambled. 
  2. Always Backup your Data: Do not store all your information on one server; the chances are that you may not be able to access it if it goes offline. Consider backing it up on a second server this way, and you are adding an extra layer of protection.
  3. Use two-factor authentication and unique passwords: Yes, having those rules that force you to include a special character, your favourite song, and the answer to your existential crises in your password seems annoying at the time, but it makes it hard for people to guess your password! Consider having different passwords for your accounts. Please ensure you do not keep something super common to guess like yournameand123. Also, always opt for two-factor authentication when given a choice. This way, you always receive a code on your email or cellular device, giving your data an extra layer of protection, and notifying you anytime anyone tries logging in to your ID!

How Can A Start-Up Benefit From Cloud Computing?

Running a startup is always overwhelming; there is always so much to do and often not enough resources to make this transition smooth. Calculating growth at an early level can be difficult, and the needs of a startup often grow and change quite quickly. Initially, to start a business, individuals required a heavy amount of capital investment, availability, and access to the internet; however, it has changed this for the better. With cloud technology, it is possible for anyone with internet access to store, manage and share their data with the world. The number of applications available through cloud computing has benefitted startups in managing their day-to-day business needs with ease.

For example, a startup can manage its design through cloud computing applications like Canvas, automate its payroll cycle with cloud applications like HR. That provides employees with an entire dashboard to access all the essential information regarding their work life. Moving to the cloud eliminates such up-front costs, leaving businesses with more capital at hand to invest in other business plans. Cloud computing also makes it possible for startups to automate their work, focusing on more strategic tasks.
