To most of us, cloud computing is this calm place where our data stays secure and unbothered. However, the reality is that it’s way beyond peaceful and is pretty much more difficult for an organization that provides or depends on it, let alone its expenses.

The customer demand for infrastructure as a service (IaaS) is rapidly stepping up, since maintaining an on-premises IT infrastructure can be overwhelmingly costive and labor-inclusive. Not to mention how hard it is to find the top talent and experience it requires.

All that aside, you will first need to be knowledgeable enough about the cloud service solutions’ analyzing, evaluating, and designing. Therefore, you need to understand at least how the common types of cloud computing services work.

You can find below our beginner guides for the most 3 common types of cloud computing services.

• Software as a service (SaaS)
• Platform as a service (PaaS)
• Infrastructure as a service (IaaS)

IaaS definition

Infrastructure as a Service (IaaS) is one of the cloud computing services where users rent IT infrastructure through the internet.

The IaaS Infrastructure is hosted on the public cloud and private cloud instead of an on-premises data center.

The service provider is the one responsible for fully managing that infrastructure and delivering it to the customers.

IaaS Advantages

IaaS has many advantages that include but are not limited to:

Improved security:

The cloud service provider of your IaaS can grant you better applications and data security than your in-house one.

Swift apps delivery:

Get the new applications to your users faster with IaaS, as you can focus on the delivery of the app and let the provider set up and infrastructure and development for you.

Target the essence of your business:

Allow your team to prosper freely by focusing on the main thing, instead of the IT infrastructure.

Overall increase:

With the right agreement, your IaaS provider can troubleshoot any potential software/hardware problems for you, moving with what’s best to increase both your stability and reliability.

Best cost-effective improvements:

Get the required product’s infrastructure in no time with scaling up ability, disaster recovery, and high availability. All at the level of start-up expenses.

IaaS challenges

Even though Popular IaaS providers include Microsoft Azure, Amazon Web Services, and Google Compute Engine. Nothing’s perfect without its drawbacks. That include:

Compromisable security:

While it’s true that the IaaS providers will provide the infrastructure, there’s no decisive telling for what comes next, since it becomes the responsibility of the business itself.

Merged vendors:

Your IaaS provider might go out of business at any moment, giving you hard time and current system interaction challenges.

Surprising costs:

whether it’s a piled-up fee or a sudden peak, the overall cost can be unexpected at times.

IaaS vs VPC

Companies with strict or sensitive data require additional protection and privacy within a public cloud, that’s where the virtual private cloud (VPC) comes into play.

VPC is the best way of isolating your data without sacrificing speed or functionality, as VPCs create you a private network for a single tenant inside the public cloud, which allows you to control the virtual firewalls, subnets, and security groups among other network privacy aspects.

IaaS glorified

IaaS providers offer gigantic services that manage to capture the interest of most business owners. However, always prioritize and check thoroughly your IT department’s capabilities to determine whether you’re ready to deal with the demands of IaaS implementation.

After accurate evaluation and analysis, you are ready to take the next step, which’s to start looking for your next IaaS provider, who will be able to meet your current and upcoming needs.

It gets easier every day to get confused between the cloud deployment models. One hour you have a public cloud, the next is a private cloud, and then you end up with a hybrid cloud?

Whether it’s the public cloud’s expectations vs. reality and why it’s probably your best cloud deployment, up to the easiest-explanation for the complicated/mixed hybrid cloud deployment. We have taken it upon our shoulders to dissect every single model for you.

A private cloud is a cloud architecture that is dedicated to a single organization. It allows organizations to use their own infrastructure that can be hosted within or outside them.

The private cloud shares some essential appearances with the public cloud. For instance, it has virtualization capabilities with computing resources, and it is scalable.

Now that you know that a private cloud is one of the leading cloud deployments, here are the top 5 reasons why it became one and why it can be your most suitable cloud deployment option.

1-Choose your desired machine

Private clouds allow you to choose the most suitable hardware/software for your needs, unbound to a limited stock that a cloud provider has to offer.

No matter what you end up with, a private cloud can run virtual machines, promoting itself as a number one option for maximizing hardware usage.

2-More cost-effective than ever

A private cloud does scale indeed automatically, but unlike a public cloud, the cost of the private cloud doesn’t grow as the service scales up.

Introducing at the same time the self-service system: granting users the ability to access the private cloud without IT complexities.

That is one of the most significant reasons for a business to consider a private cloud, as it’s easier to scale up and provide extra services, even without additional configuration required by the IT team.

3-Absolute security & privacy control

The improved security level of private clouds is more significant compared to the public cloud, as all your files and data are saved/managed on servers accessible only to your company (single-tenant environment).

Apart from increasing the data privacy levels, your organization doesn’t need to worry about the physical security of the infrastructure if your server is on-site.

Also, suppose your servers are located in a data center. In that case, they will be accessible by your same internal IT team through a highly secure network instead of the unsecured regular internet connection.

Beware, it is your IT department that will be held accountable at the end of the day for any potential wrongdoings or, for example, sensitive data leaks to third-party providers.

4-Transformation to a hybrid cloud

It’s no secret that private cloud users will at some point need to migrate to a hybrid environment to meet all their needs and get the best of both worlds (public and private clouds).

Enjoying all the private cloud benefits in addition to the public cloud features indeed is tempting, and guess what?

Going from a private to a hybrid cloud is way easier than going from a public one, as choosing the public cloud first may highly limit your infrastructure choices.

5-Efficiency & availability

Private clouds are not-only pretty much available everywhere across the world, which is more than what can be said for a public cloud. But also, they can be hosted on privately hosted environments, giving you:

• more control over your data and infrastructure
• prompt interference for any critical changes needed
• accurate application monitoring and analytics to both predict and prevent any downtime.

• What’s the difference between a VPC and a VPN? The definitive answer

We’ve all been there, asking the same question over and over. Can just one other word make so much difference?

The lines between the private cloud and the virtual private cloud are blurring more than ever. Still, they differ in terms of provider, architecture, and resource delivery.

Luckily you can decide between both based on these distinctions.
Without further ado, let’s dive into it!

Private clouds: what to expect

Private clouds stand by their name as a computing service offered through the internet, exclusively provided to one organization, and dedicated to fully-protect it from any harm.

Unlike a public cloud’s often misassumptions of its expectation vs. reality. A private cloud is direct to the point, only available to a set-of selected users (single-tenant environment).

The internal/corporate/private cloud is easy to scale up. Therefore, it can provide:

• Scalability: providing extra services without extra configuration to be required by the IT team
• Self-service: granting users the ability to access the private cloud without IT complexities.

You better know that your own IT department will be held accountable for any failures and met with many complexities. So, you should invest smartly into the management, staff, and other maintenance expenses.

Benefits of private cloud

With optimal security and customization control, the advantages of a private cloud may include:

Full software/hardware choices control: choose what you prefer, not what a cloud provider offers.

Full conformity and flexibility: customers aren’t forced to obey a cloud service provider’s administration

Don’t forget to keep in mind that one of the most distinguished traits private clouds enjoy is the high privacy/security level, protecting you against any potential attacks or from sensitive data leaks to third-party providers.

Alongside elasticity and additional control, using the dedicated resources hosted on-premises.

Cloud services for private clouds

Two cloud services models are applicable for a private cloud, which are the IaaS and the PaaS.

Platform-as-a-Service (PaaS): where a third-party provider develops platforms and exposes them to customers over the internet. As if you’re buying the tools you need to build your house by yourself.

Infrastructure-as-a-Service (IaaS): where a third-party provider hosts virtualized resources online to customers. As if you’re renting land to build your house on, but still need your own building equipment to do so.

Private cloud and the next level

Capable of running virtual machines, private clouds are a solid choice to maximize hardware usage.

Still, private cloud users will need more public cloud features and will often mix both the public cloud and private cloud to develop a hybrid cloud that can have the necessary elements to meet all their needs.

Deploying a hybrid cloud is essential for ultra-efficiency purposes, and will benefit you greatly by freeing up space using cloud bursting.

Virtual private cloud (VPC)

A virtual private cloud is a private cloud within a public cloud, reinforced with security/isolation aspects using public cloud resources.

Same as the private cloud, you’re only allowed to access it if you’re the one who made it or a part of the people invited inside (multitenancy).

The VPC comes backed with scalability, agility, exquisite performance, and easy hybrid cloud deployment using an application programming interface (API). Thus, Making-your business inevitably one step closer to perfection.

What isolates a VPC

With firewall functions that provide filtering capabilities, here’re the technologies behind the VPC isolation:

Subnets: You reserve IP network addresses so you can come back later to, which are ultimately only yours to command, away from the evil public internet world.

VLAN: VPCs can be isolated through some devices connected to a local area network, which means having a connection that is there without the use of the internet.

VPN: mostly used to access region-restricted websites or to shield your browsing activity. VPNs isolate a VPC using encrypted traffic. A virtual private network (VPN) passes through a publicly shared Internet infrastructure that’s not visible to anyone but you.

VPC top benefits

Most viable and valuable VPC scenarios come into play when you need the following:

Guaranteed customer satisfaction: a VPC helps you build brand trust/customer loyalty, and therefore gain more traffic and achieve other strategy goals, with an uptime ratio up to 99.99%.

Exceptional security: a VPC offers you a complete data separation from your provider’s other clients unless you give them access, protecting all your valuable information from potential leaks to the wrong hands.

Customize all you want: with complete control over your network, VPCs allow you to connect to your enterprise at any time you wish to, add segmentations based on your mere desire, and become more agile than ever.

Challenges VPC users to face

Like all the beautiful things in the world, they pack a punch when they come with a bit of excitement. Rare but possible at the same-time VPC challenges might include:

1-Complexity issues when trying to manage and configure the VPN of the VPC you are using. Therefore, you should have a pretty solid IT team for viable incidents.

2-VPCs, no matter how great they may seem, are still hosted outside the enterprise’s data center. This exposes some strict compliance businesses to data and application limitations.

Virtual private cloud vs. private cloud: you don’t have to choose

Although they are often used by financial institutions, government agencies, or other organizations with critical operations seeking more and improved control over their environment.

The utter truth is that no one specific type of cloud computing can be considered the right choice for everyone and will always depend on each entity’s needs.

As technology progresses faster than ever, several other cloud computing models and services have evolved to meet the fast-changing individualized needs of organizations.

There will be ups and downs for every cloud deployment model, but the three main service models for deploying a cloud service are a private cloud, public cloud, and hybrid cloud.

Strategize, organize, and study both your needs and your competitors as hard. That way, it’s easier to grasp the ultimate end goal and move swiftly towards it using the perfect deployment method, mainly directed and guided by your unique business needs.

Public cloud’s often on top of the list of cloud deployments, but is it really worth it?
Today, you and I aren’t just gonna shed some light on the basic needs but also take a behind-the-scenes look at the public cloud overall.

Public cloud explained

Simple enough, offering scalability/resource sharing that’s beyond a single organization’s ability, and making resources available online to the public, are a public cloud’s job.

Whether free or costly, these public resources vary from one provider to another, including applications, virtual machines, etc.

Obviously, the more resources you require, the higher the price gets. That’s why it’s advised to develop a wise strategy for vast amounts of data before choosing your cloud vendor.

Public cloud competitors

Unlike the private cloud that offers higher security due to earmarking specific users’ resources, or the hybrid cloud environment extends a private cloud to the public cloud to get the best of both worlds.

Public clouds don’t offer the same level of security or the same resources’ optimization enhancements, but cloud computing in general indeed has its benefits!

Public cloud distinguishments

Allowing you to scale at a near infinite rate without committing to expanding your physical IT infrastructure, public clouds will enable you to purchase a virtual desktop license and instantly locate it anywhere!

Also, public cloud data is backed up safely and is accessible from the same “anywhere” we mentioned earlier. Additionally, using the public cloud saves businesses money through lower costs for their purchase and maintenance equipment.

If you still need more, just wait till you know that the most significant -and most popular- providers like Microsoft Azure and Google Cloud Platform offer per-per-usage deals!

Per-per-usage deals grant organizations the ability to pay only for the resources they use, helping them to maintain and protect their budget.

Public cloud structure

As u must have guessed by now, public cloud architecture is completely virtualized.

Besides protecting your data, you can access a service or application on any internet-connected device.

Designed with built-in redundancies to prevent data loss, public clouds may be structured differently according to the type of service provided.

Here’re the most common 3 cloud service models in the market today.

Software-as-a-Service (SaaS): where a third-party provider hosts/makes the applications public and available over the internet. More like renting a house. It’s not yours, but you use it as it’s yours anyway. “Gmail”

Platform-as-a-Service (PaaS): where a third-party provider application development platform exposes them to customers over the internet. More like buying the tools needed to build your house yourself. “Microsoft Azure”

Infrastructure-as-a-Service (IaaS): where a third-party provider hosts servers and other virtualized resources online to customers. More like renting land that you can build your own house on, but you still need to have your own building equipment. “Google Compute Engine”

Bonus: everyhing-as-a-Service (XaaS): generally stands for services related to the cloud computing/remote access world. It represents the tools and technologies available to be delivered to users, paid or unpaid, over the internet.
