What is Cloud Computing? Growth Hack Your Way To Success

Cloud Computing, Everyone is talking about this, But what does it mean? In this blog, I’ll try to answer all your queries, So that you can understand the power and benefits of the cloud. If you’re a big company, you need some computers to store your data and run your software applications. So you get a server room. It might look like this:

Cloud Servers

Instead of having to maintain all those servers, you can pay for someone else to do it. There are public vendors like Amazon, Microsoft, and Google that offer this as a service. Then your data is in their server room, which might look like this:

server cloud computing

You don’t know exactly which servers your data is on. You just know that they have allocated some servers for you automatically based on your needs. This is cloud computing.

Basically, you can define it as renting resources, like storage space or CPU cycles, on another company’s server. You have to pay only for what you use. The company providing these services is referred to as a cloud provider.

History of Cloud Computing

Though the internet was started in the 1960s, it was only in the 1990s when the potential of the internet to serve enterprise was discovered, which then led to further innovation in this area. As the connectivity and transfer speeds of the internet got better, it gave a solution to new sorts of firms known as Application Service Providers (ASPs).

ASPs took the existing enterprise applications and ran them for the business using their own machines. The clients would pay a month-to-month charge to run their business over the internet from ASP’s systems.

But it was only within the late 1990s that cloud computing as we know it today, emerged. The cloud computing service has grown almost 80% year-over-year in the last two quarters and is on the step to hit $7.8 billion in revenue in 2015, 4 times the 2012 gross sales of $1.8 billion.

Interesting, ain’t it?

Now that you have got a good idea, what cloud is, simply take into consideration all of your daily actions online, and you’ll understand that quite a lot of your work that you just do online relies on the cloud. Like all the social media interactions and video streaming websites are all on the cloud, something that you just store online is again cloud, you paying your electrical energy bills online, online shopping, everything!

Let me explain you with an example,

Consider you planned to host a Hotel booking service. Before the cloud, you had to buy a physical server and host it. So at any time when a customer wants to book a hotel, he sends a request from his device to the server. The server processes the request sent by the customer and sends data back to the consumer (customer’s pc). If the server and the consumer were having a chat, it would look like this.

Client: I would like a book for the XYZ hotel.

Server: Here are the available rooms for the hotel {101, 102, 103, 104 …}

Client: I’m booking 101, 102

Server: Blocking the rooms, awaiting payment

Client: Here are my card details {CardNo: XXXXXX, CVV…}

Server: Congrats, they are booked.

The customer’s pc and the server communicate with packets of data.

Your server would be capable of deal with 1000’s of such requests based on its configuration.

However, what occurs when the demands exceed the server’s limit? Say 10k — 20k requests? It is a similar case when ten to twenty persons are pinging you on Whatsapp. You will try and reply to all of them one after the other. However, you would take plenty of time. However, on the internet, this delay is unacceptable.

Why can’t we add extra servers?

Yes, that’s an answer. Say you purchase or rent ten extra servers. Now they will work as a group and share the load. That works effectively. However, your service won’t have such requests on a regular basis. Compare to some holiday or vacation time. The variety of requests drops down. The extra servers you purchased are actually jobless. You can still be paying for their electricity and bandwidth. In some conditions, you possibly can never predict when requests are at a peak. So it’s needed for the servers to be prepared. When the subsequent peak time arrives, your servers could also be outdated. Hosting it physically has lots of different issues like power outages, maintenance costs, and so on. Since this includes wastage of resources, this isn’t an efficient solution. The cloud was developed to deal with this.

The cloud provider is accountable for the physical hardware required to execute your work, and for keeping it up-to-date. The computing services provided are likely to vary by the cloud provider. However, usually, they include:

  • Compute power– such as Linux servers or internet applications
  • Storage– such as files and databases
  • Networking– such as safe connections between the cloud provider and your organization
  • Analytics– such as visualizing telemetry and performance data

Types of Cloud Computing

Types of Cloud Computing

Public cloud

This is the most common deployment model. In this case, you don’t have any local hardware to manage or keep up-to-date – everything runs on your cloud provider’s hardware. In some cases, it can save you extra money by sharing compute resources with other cloud customers.

Businesses can use any public cloud providers of various scales for there deployments. Microsoft Azure is one example of a public cloud provider from Microsoft.

Advantages

  • High scalability/agility – you do not have to purchase a new server in order to scale
  • Pay-as-you-go pricing – you pay just for what you utilize, no CapEx prices
  • You’re not answerable for hardware updates and maintenance.
  • Minimal technical knowledge is enough to set up and use – you’ll be able to leverage the skills and experience of the cloud provider to make sure workloads are safe, protected, and highly available

A typical use case situation is deploying an online software or a blog web site on resources or hardware that are owned by a cloud provider. Using a public cloud on this situation permits cloud customers to get their web site or blog up quickly, after which they can focus on maintaining the website without having to worry about purchasing, managing, or maintaining the hardware on which it runs.

Disadvantages

Not all situations match the public cloud. Here are some disadvantages to consider:

  • There could also be particular safety necessities that can not be met through the use of public cloud
  • There could also be authorities policies, trade requirements, or legal requirements which public clouds can’t meet
  • You don’t own the hardware or services and can’t manage them as you could wish to
  • Unique enterprise requirements, such as having to maintain a legacy application, could be hard to meet.

Private Cloud

In a private cloud, the company create a cloud environment in their own datacenter and supply self-service access to compute resources to customers in an organization. This provides a simulation of a public cloud to your customers. However, you stay completely responsible for the purchasing and managing of the hardware and software program services you provide.

 Advantages

This method has a number of benefits:

  • Private clouds can meet strict compliance, security, or legal requirements
  • You can make sure the configuration can help any scenario or legacy application
  • You have control and responsibility for security

Disadvantages

Some reasons that teams move away from the private cloud are:

  • You have some introductory CapEx prices and should buy the hardware for startup and maintenance.
  • Owning the equipment limits the agility – to scale you need to purchase, install, and set up new hardware
  • Private clouds require IT expertise and experience that is hard to come by

A use case situation for a private cloud would be when a company has data that can’t be put within the public cloud, maybe for legal reasons. An example scenario could also be where government policy requires specific data to be kept in-country or privately.

A private cloud can provide cloud performance to external customers as well, or to specific internal departments such as Accounting or Human Resources.

Hybrid cloud

It is a combination of private and public clouds, permitting you to run your applications in the most appropriate location. For instance, you would host a website in the public cloud and link it to an extremely secure database hosted in your private cloud or on-premises datacenter.

This is useful when you have some things that can not be put in the cloud, maybe for legal reasons. For example, you might have some specific pieces of data that can not be exposed publicly (such as medical data), which must be held in your private datacenter. Another example is a number of applications that run on outdated hardware that can’t be updated. In this case, you’ll be able to maintain the outdated system running in your datacentre, and connect it to any public cloud for storage or authorization.

Advantages

Some benefits of a hybrid cloud are:

  • You can maintain any systems running and accessible that use out-of-date hardware or an out-of-date operating system
  • You have flexibility with what you run locally versus within the cloud
  • You can benefit from economies of scale from public cloud suppliers for services and resources where it is cheaper, after which supplement with your own equipment when it’s not
  • You can use your own equipment to fulfill security, compliance, or legacy scenarios where you need to completely control the environment

Disadvantages

Some issues you will have to watch out for are:

  • It might be more expensive than selecting one deployment model because it involves some CapEx price upfront
  • It might be more sophisticated to set up and manage resources.

 Why move from On-premise to Public Cloud

There are a variety of advantages to shifting from on-premise technology to cloud-based technology.

Of course, which benefits you take into account will depend on lots on how you’re using it. Are you utilizing cloud computing as a consumer? Are you utilizing it for your online business? This is essential because the benefits are completely different for each.

Cloud Computing for Consumers

  • If you use any of the Google Suite apps or things like Dropbox or Netflix, then you’re already using cloud computing!
  • Cloud computing is only a method so that you can use the technology of others, often over the internet. With Dropbox, you’re utilizing their servers to store data. Instead of utilizing the internal memory of your personal laptop, or your own hard disk, you’re utilizing theirs. With the Google Suite, you’re utilizing their programs, regardless that you didn’t set up them on your laptop.
  • As a consumer, you would possibly already know its advantages. The services offered are often free or available at a low price. It is convenient to make use of. And the software program is up to date with none effort from you.

Cloud Computing for Businesses

  • The advantages of cloud computing are just a little completely different for companies. This is as a result of companies have a different perspective. Cloud computing isn’t just a tool to make use of; it’s a way for the enterprise to generate profits. What this implies is that the choice to make use of cloud computing might be primarily based on how it will help the business earn money.
  • One of the principal advantages is that cloud computing options for companies are often a subscription-based model. This is especially good for small companies, which tend to have less capital. You will not have to purchase a variety of hardware just to handle the data of your online business.
  • Another good thing about cloud-based options is accessibility. You will not have to worry about lost hard drives or damaged laptops in the workplace. Because the data is within the cloud, you possibly can access it from any system

Cloud computing could be very helpful for companies and individual customers alike. You simply have to check the pros and cons.

Types of cloud providers: IaaS, PaaS, SaaS, and Serverless

Most cloud computing services fall into 4 broad classes: Software as a Service (SaaS), Platform as a Service (PaaS), Infrastructure as a Service (IaaS) and Serverless. These are typically known as the cloud computing services or computing stack as they are built on top of one another. And knowing about this model will help you to decide which model can make your business objectives easy to construct.

Cloud Services

1. Infrastructure as a service (IaaS)

Infrastructure as a Service is probably the most flexible category of cloud services. It aims to offer you full control over the hardware that runs your application (IT infrastructure servers and virtual machines (VMs), storage, networks, and operating systems). Instead of purchasing hardware, with IaaS, you lease it. It’s an instant computing infrastructure, provisioned, and managed over the internet.

2. Platform as a Service (PaaS)

Platform as a service indicates cloud computing services that provide an on-demand environment for developing, testing, delivering, and managing software applications. PaaS is designed to make it simpler for developers to rapidly create web apps or mobile apps, databases, and other network services without worrying about setting up or managing the underlying infrastructure of servers, storage, network, and databases required for the development.

3. Serverless computing

Serverless computing focuses on creating app functionality without spending time, continually maintaining the servers and infrastructure required to do so. The cloud provider handles the capacity planning, setup, and server management for you. Serverless architectures are extremely scalable and event-driven, only using resources when a particular function or trigger happens.

4. SaaS: Software as a Service

It simply means running applications at public clouds. The user makes use of these apps through the Internet. These apps are maintained by the Service Provider. Some, e.g., of Service Providers are SalesForce, Microsoft(Office 365), Oracle, Google(Google Apps), and so on.

Salesforce was the first firm to transform the world of Saas, and from that point, different companies have seen potential on this market and launched their apps.

Advantages and Diadvantages

Top Advantages of Cloud Computing

Cloud computing is a giant shift from the standard method companies think about IT resources. Here are seven frequent reasons organizations are turning to cloud computing services:

1. Cost

Cloud computing reduces the capital expense of purchasing hardware, software program, and setting up and running data centers—the racks of servers, the 24 by7 electricity for energy and cooling, the IT specialists for managing the infrastructure.

2. Speed

Most cloud computing companies are provided self-service and on-demand, so even huge quantities of computing resources will be provisioned in minutes, sometimes with just some mouse clicks, giving businesses a whole lot of flexibility and taking the strain off capacity planning.

3. Global scale

The advantages of cloud computing companies embrace the flexibility to scale elastically. In cloud speak, that means delivering the correct quantity of IT resources—for instance, more or less computing power, storage, bandwidth—right when it’s needed and from the appropriate geographic location.

4. Productivity

On-site datacenters sometimes require a whole lot of “racking and stacking” hardware setup, software program patching, and different time-consuming IT administration chores. Cloud computing removes the necessity for a lot of those duties, so IT groups can spend time on reaching extra important enterprise objectives.

5. Performance

The largest cloud computing companies run on a worldwide community of secure data centers, that are commonly upgraded to the newest technology of fast and environment-friendly computing hardware. This gives a number of advantages over a single company datacenter, including lowered network latency for applications and higher economies of scale.

6. Reliability

Cloud computing makes data backup, catastrophe restoration, and business continuity simpler and less expensive as a result of data can be mirrored at a number of redundant sites on the cloud provider’s network.

7. Security

Many cloud providers provide a broad set of policies, technologies, and controls that strengthen your security posture overall, serving to defend your data, apps, and infrastructure from potential threats.

Disadvantages of Cloud Computing

There are benefits from cloud computing usage; however, it’s undeniable that this method also has some drawbacks. The risks involved with cloud computing you should know, such as:

1.Risk of data confidentiality

There is all the time, a threat that user information can be accessed by a different user. So there will always be a fear of data protection.

2. Depends on the Internet connection

The internet is the only way to use cloud computing. When there is no internet connection in your place or the internet path to the cloud provider is in trouble, automatically access to your cloud computing machine might be disconnected. Now that is the place the most important obstacle is happening in developing countries and remote areas that do not have good internet access. And the weak spot of the public cloud is where everyone accesses the same server and server and can increase the risk of attack, and down the server.

3. Data Mobility

This refers to the potential for sharing data between cloud providers and how to retrieve data if, in the future, the user makes a process of terminating cloud computing services. And there is local storage where the data can be used at any time as needed.

4.Low Connection

It does not work nicely if the connection is slow. The quality of cloud computing servers is among the most important considerations before we decide to provide a cloud computing server service. When the server is down, or the performance isn’t good, we will be harmed because of poor server quality.

5. Security

Cloud hacking cases, the past few months have proven that not all cloud suppliers are as safe as they declare to be. As an enterprise, you can’t afford to have sensitive details about your organization or your clients fall victim to hackers. One of cloud computing’s best disadvantages is that you don’t always know which providers you can trust.

This cloud computing drawback is common to SaaS providers than with Hosted services. Because of the popularity of SaaS services, they get targeted more often, and more simply, than a Hosted provider.

Future of Cloud Computing

Cloud computing and the tech behind it, there are a lot of potential opportunities and capabilities. Cloud computing can open an entirely new world of jobs, services, platforms, applications, and far more. There are so many possibilities beginning to form as the future of cloud computing begins to take off. For instance, distributors and service providers can get on board to develop new and alternative ways of selling their products and companies to the cloud customers via the cloud expertise. It opens up an entirely new platform for designers and internet builders. Businesses and organizations can set up themselves and conduct enterprise far more reasonably priced and professional. Social networking and retaining in contact with buddies will get an incredible deal more straightforward and effective.
