What is Disaster Recovery as a Service?

Disaster Recovery as a Service (DRaaS):

A cloud computing service that allows the user to back up their data and assets by providing third party-services, and in the case of failover, it includes data recovery. This backing up data and IT infrastructure are known as Disaster Recovery as a Service (DRaaS). The organization does not have to arrange all the resources independently; it relies entirely on the DRaaS provider’s services and resources.

Working of Disaster Recovery as a Service:

DRaaS provides disaster recovery by backing up the data and assets in virtual locations. This whole process includes the following key steps:

  • Replication:

The assets and the data on the primary site are replicated, and that replicated data is transferred to the remote and virtual environment established by the DRaaS. The replication process must include the physical and virtual servers. To avoid data loss at the time of failover, DRaaS should take snapshots of the data and assets time by time.

  • Failover:

The speed is the primary and significant factor at the failover time because it determines the amount of data loss and recovery.

  • Failback:

After the failover, it is mandatory to restart the replication process as soon as the completion of failback.

Need of Disaster Recovery as a Service:

Disaster Recovery as a Service

Followings are the main five reasons for an organization or enterprise to go for DRaaS:

  1. Security-related attacks
  2. On-premises power outages
  3. Network or hardware failures
  4. IT system, software, or application errors
  5. On-premises data center failures

Due to the reason mentioned above, every organization and business needs DRaaS. DRaaS provides the best data backup and recovery services at the time of the disaster.

Disaster Recovery as a Service Model:

There are mainly three models for DRaaS available to the customer organization, such as:

  • Assisted Disaster Recovery as a Service:

This type of DRaaS model fits the organization’s customized software and applications. The Assisted DRaaS is responsible for providing IT expertise and services to optimize and enhance the disaster recovery plan. 

According to the requirement, the customer independently or dependently implies the disaster recovery plan, assisted DRaaS.

  • Managed Disaster Recovery as a Service:

The Managed DRaas model is the best for an organization that lacks IT expertise and time. In managed DRaaS, Disaster Recovery service providers are fully responsible for resources, services, management, optimization, and infrastructure and application changes. The customer is not responsible for any Data Recovery plan or benefits.

  • Self-service Disaster Recovery as a Service:

If your organization has experienced and specialized IT expertise and disaster recovery personnel, then the self-service DRaaS model is the best fit. It is the most reasonable and affordable model as the customer has to manage, optimize, monitor, test, examine, and plan the disaster recovery itself. The customer has to host IT infrastructure, hardware, software, and other resources on its own.

Pros and Cons of DRaaS:

DRaaS has its pros and cons simultaneously. Advantages and disadvantages of the DRaaS include the followings:


Pros of DRaaS are as followings:

No duplication of storage:

While availing DRaaS services, there is no duplication of storage hardware in the data recovery center and primary data center.

Relaxed in-house IT staff:

The IT staff is free of backup and data recovery worries and can focus on other responsibilities.

No need for the secondary data center:

DRaaS excludes the need for the secondary data center for recovery and backup purposes.

Provision of Data Recovery Capabilities:

It provides data recovery capable expertise and specialists to establish an effective and enhanced data recovery plan.


Disadvantages of DRaaS includes the following:

Rely on service providers:

The most significant disadvantage of DRaaS is that the customer has to rely on the service providers at failover or disaster.

Trust the disaster recovery services:

The organization must trust the DRaaS service providers to implement the infrastructure and disaster recovery plan. The organization has to entrust the DRaaS service providers to meet the organization’s recovery time objective and recovery point objective.

Potential performance issues:

Cloud applications and software may experience performance and deployment issues.

Bandwidth challenges:

There might be any bandwidth challenge while replicating data and assets.

Key considerations to choose DRaaS:

While selecting the DRaaS, the followings are the key considerations to keep in mind for any organization or enterprise:

  • Access controls
  • Assistance by the DRaaS
  • Reliability of the DRaaS

Cost of DRaaS:

The cost depends on the model you select. DRaaS is very reasonable and cost-effective. Your organization has to pay for the services monthly. If any organization does not invest in Disaster Recovery, they might lose up to $ 100,000 per hour of downtime.

SaaS vs Cloud: What is the Difference?

SaaS vs Cloud Computing is often used interchangeably. Even though they are linked and have a lot in common, there are significant differences between the two approaches.

Cloud computing has been characterized by the National Institute of Standards and Technology as “on-demand network access to a shared pool of customizable computer resources that may be promptly granted and released with no administrative effort or service provider engagement.”

Some claim that SaaS helped pave the way for cloud computing, a far more comprehensive platform on which SaaS operates. Cloud computing refers to the use of Software as a service. It’s all about SaaS (Software as a service): Software delivered to a computer via the internet.

To improve the user experience, cloud products can collect large amounts of anonymized data and use this information within algorithmic Software to enhance the user experience; for example, by making their cars drive more safely, recommending new music, or assisting you in determining the root cause of a network issue (LogicMonitor, humble brag). The advent of SaaS-based solutions is helping to usher in this new age.

SaaS vs Cloud

When it comes to Software that isn’t stored on your premises, SaaS refers to it as a service rather than a product. Instead of being a part of another software, it is a separate application.

This is hosted in the provider’s data center instead of an on-premise solution that would employ servers and storage in your own data center.

On-premises software is licensed one way; SaaS software is licensed another. Software-as-a-service means that instead of obtaining an application license and then paying for the ongoing costs of maintaining and upgrading it, an application may be “rented” for an agreed-upon period.

The SaaS application’s fees are included in the monthly subscription charge, eliminating the need to acquire and install equipment and then pay for software maintenance.

However, Cloud Computer provides computer resources not bound to a specific location. The infrastructure and services cover everything from virtual machines and servers to data storage, communications and messaging, network bandwidth, and development environments.

Concerning the debate between SaaS vs cloud computing, Developers, application providers, experienced computer users, and corporate IT departments may rent equipment and services in the Cloud rather than the general public.

Your servers must be accessible for Cloud Computing to function correctly. Whether or not your SaaS applications were built using Cloud services is immaterial; the infrastructure that supports them may have been.

When we talk about SaaS vs Cloud, it was a ‘time-sharing system’ back in the 1960s when SaaS first appeared. Many “dumb” terminals without CPUs were linked to a mainframe or minicomputer to offer centralized hosting for commercial applications.

Employees were permitted to use their PCs to run applications, but the company’s central server was still storing the most critical information. SaaS has regained its attractiveness because of a reduction in bandwidth costs.

SaaS and Cloud Differences

saas vs cloud

Because of SaaS, the Cloud has expanded into a larger platform for SaaS. A single usage of Cloud Computing that goes beyond just delivering Software is Software as a Service (SaaS).

All of your data will be held by your service provider if you choose a SaaS solution, such as Dropbox. You have no control over what your service provider may and cannot do with your data.

As opposed to traditional methods of storing data, cloud computing allows you to have more control over your data.

Even if the servers aren’t close by, you can still manage the Software and its data. You may migrate your cloud storage data to your storage at any moment.

High-value apps will likely be moved to the Cloud by Cloud software, while SaaS is projected to continue dealing with free or low-cost apps and services.

Cloud computing differs from SaaS because it is hosted on a customer-owned server, while SaaS requires a third-party host. Your data may be used in any way the service provider deems fit without your consent.

Data ownership and security benefits outweigh the negatives in most cases when using SaaS. SaaS applications need a user to first log into their vendor’s website. 

Even though SaaS applications are hosted “on the cloud,” the Cloud is not synonymous with SaaS itself. For example, a free email service processes and keeps our data for us.

Most of us will continue using the service even if we don’t know about the company’s privacy policies. Your data may be more easily managed on the Cloud.

While the servers themselves may not be in the same place, data and Software may be backed up and saved on the Cloud. The data is yours after it leaves the Cloud, just as with a traditional on-premises server farm.

Final Verdict

SaaS vs Cloud Computing is a never-ending discussion. I hope you understand that cloud software solutions are often the most crucial choice for small enterprises looking for low-cost solutions. Cloud computing makes more sense for larger firms with more in-house capabilities and a need or desire to have more control over sensitive data.

These organizations can also afford the infrastructure expenditures readily. In other words, as the Cloud’s capabilities grow, so does its complexity. There may be a separation between on-premises and cloud-based infrastructure, platforms, and services.

AWS vs Google Cloud vs Azure Market Share

Nowadays, cloud computing has become an essential part of modern data storage and manipulation. It is important for data protection, data storage, and performing tasks on that data. There are two main cloud computing types: Public cloud and Private cloud. 

The public cloud refers to the cloud services that an individual or an organization receives via the internet.

All the cloud reserves are stored on the cloud servers of the vendors, and the necessary services can be easily accessed from there. It can also be provided to multiple customers simultaneously and hence is named a public cloud.

Whereas private cloud solutions refer to cloud services that are completely designated to an individual or an organization. No other person is authorized to access that.

They are hosted by private cloud systems provided by the vendors and the cloud service providers. More than one customer cannot use a private cloud at a single time. In this topic, we discuss will AWS vs Google Cloud vs Azure Market Share. 

AWS vs Google Cloud vs Azure Cloud Services

The fight of being the best cloud service provider is largely between the three giants in the computing world, Amazon, Google, and Microsoft. The cloud services provided by Amazon are called Amazon Web Services (AWS).

Microsoft’s services regarding cloud computing are called Microsoft Azure. Besides, Google cloud services are known as Google cloud. 

This article also describes the in-depth differences between the three companies and their cloud services. 

AWS Cloud Services

AWS and Amazon are generally dominant compared to Microsoft and Google when it comes to providing complete cloud services and their overall maintenance. They are also the leaders in market shares as AWS and Amazon hold 33% of the market share in the cloud world. 

AWS has a vast toolset that continues to grow each year, and its dominance is unmatched yet. However, the services they provide can often get costly. 

Advantages and Disadvantages of AWS

AWS vs Google Cloud vs Azure Market Share

Huge Scope

When it comes to cloud computing and providing cloud services, AWS has a huge scope, and no other company comes close to them regarding the variety and amount of cloud services they can provide.

Most Experienced

As the pioneers in starting general cloud services, Amazon and AWS possess more experience than any other company. They only are reputed quite highly.


Probably the weakest point of the AWS cloud services is the cost of their operations and how they are far more expensive than any other cloud service provider in the market.

Although the standard and quality of the products and their work are very high for many people, it can get too expensive.

However, the pros of the AWS cloud services far outweigh the cons and make it a leader in the AWS vs. Azure vs. Google cloud market share.

Microsoft Azure Cloud Services 

Azure is the product launched by Microsoft, and it is majorly responsible for providing cloud services and acts as a cloud vendor. Azure is a close second to AWS and Amazon and has 18% of the market share. 

It gets second place in AWS vs. Azure vs. Google cloud market shares. Although Azure came quite late, its association with Microsoft proved vital. Hence it got a head start that some others may not have access to.

With the help of a leading tech company at its back, Azure is quickly transiting towards a better and more advanced cloud service vendor.

Advantages and disadvantages of Azure cloud Services

Affiliation with Microsoft

Azure’s affiliation with a company like Microsoft proves to be vital. Hence a lot of the customer and market of Microsoft is shared by Azure. The clients and customers trust Azure to be on the standards as they already have built trust with Microsoft.

Operational Costs 

Unlike AWS, Azure has way fewer operational costs and is a more economical approach to customers and clients.


One of the major reasons for Azure’s downfall is the variety they possess, and although the quality is up to the mark, the lack of vast features and variety is a big miss.

Google Cloud Services

Google is a leading tech giant globally and has also launched its cloud services known as Google cloud. Google cloud services are also highly appropriate for individuals and companies looking for a small number of cloud storage and services that are economical and user-friendly. 

Google cloud services are ranked third in the AWS vs. Azure vs. Google cloud market share. Google’s cloud services are all developed and maintained by Google itself. They have a high reputation in the market but are not quite enterprise-centric like the rest.

Advantages and Disadvantages of Google Cloud Services:

High Compute Offerings

Google cloud services offer high computing offerings to their customers and the organizations that partner with them. The services that they offer range from Big Data to Data Analytics and their cloud platforms.


The operational costs of the services provided by Google regarding the cloud are quite affordable. Organizations and companies prefer the services provided by Google just because of this fact alone.

Not Enterprise Friendly 

The major downside of the cloud platforms and services provided by Google is that they are not enterprise-friendly and don’t give much effort into working with enterprises. Hence, a huge market of enterprises that need cloud services and are thinking of shifting towards the cloud is not fond of them.


The major three competitors in the cloud world are Amazon, Microsoft, and Google. The cloud services they provide are of high standards, but they all have their pros and cons. It is all dependent on the client and customer’s choice and needs to decide which one is better. 

However, the market share of AWS is more than Azure and Google at 33% and leads the race in AWS vs Google cloud vs Azure market share. 

What is Multi-Cloud Architecture?

So before moving ahead with our questions and concerns, let’s have a quick look over the basic concept of exactly what is multi-cloud architecture.

What is Multi-cloud Architecture: Check its Business Benefits

A multi-cloud architecture leverages services from various cloud providers to gain business benefits such as increased innovation, access to specialized hardware that is not accessible on-premises, and the capacity to extend computation and data storage as the organization grows.

A multi-cloud approach may include a combination of public cloud and private clouds or numerous public cloud providers working as one.

Resilience is provided through a multi-cloud architecture. Using a dispersed distribution for apps allows you to use cloud computing environment characteristics for maximum efficiency.

With the help of various clouds and services and adapting apps to their capabilities will always result in more efficient and better outputs. For instance, one cloud’s superior GPUs for specialized workloads and a separate cloud’s best-in-class analytical engine.

A multi-cloud architecture is logical for a variety of reasons. You may employ the newest innovations in technologies and services, adopt a pay-as-you-go approach for the resources you utilize, and migrate across clouds as they compete in an advanced environment and pricing by utilizing the best cloud for each job.

By splitting your workloads, you may save expenses, increase resilience, and protect your sensitive data. 

The Benefits of a Multi-Cloud Architecture

Now the question is “Why Should You Use a Multi-Cloud Environment?”. And the answer cannot be given in a single line. Risk management is a key benefit of a multi-cloud architecture. If one cloud provider’s system goes down, you may instantly switch to another vendor until the service is restored. Viola – Problem solved!

There are, however, additional advantages to employing a hybrid multi-cloud architecture. Let’s dive into the details:

  • If business users are dispersed, adopting different cloud service providers due to proximity might boost performance.
  • Because your leading cloud provider may not have a footprint in places where data must be kept in-country, using a second cloud provider there will satisfy data localization rules.
  • Keep your research and deployment processes separate from your manufacturing environment.
  • Adding public cloud features and scalability to data centers
  • Keeping seller lock-in at bay
  • Hosting programs at the most convenient location for end-users

Deploying in a Distributed Environment

Tiered cloud migration of programs and data can be cost-effective to handle your resources.

Multi-cloud strategies and hybrid multi-cloud architecture are frequently used by businesses to operate mission-critical and confidential apps in a cloud infrastructure while shifting less essential tasks to a public cloud for enhancing overall performance.

Hybrid Cloud on Multiple Levels

In a multi-cloud scenario, you may wish to isolate front-end apps from backend applications.

Applications for the Front-end

Front-end apps are closest to end-users and require frequent changes. These apps often handle the client or user interface but do not directly hold large quantities of data.

This is required for keeping the user engaged on your site for a longer time.

Application for the Backend

Backend apps, on the other hand, are usually all about data. It must be managed and secured. Front-end apps would be moved to the public cloud in a layered hybrid cloud system, whereas backend applications would be kept in a more encrypted VPN cloud and on.

Some workloads, such as data for analytics that is transferred up to the cloud for processing because the latency to draw from on-premises servers is too high, are better suited to the cloud. Other data is more sensitive or subject to compliance laws, necessitating on-premises storage.

Final Verdict – What Can It Bring To Your Business?

Now, you must have understood what is Multi-cloud Architecture, its use, and its benefits. Establishing a multi-cloud approach offers several business benefits if firms take the time to develop and create the necessary architecture.

Too many firms shift to multi-cloud on the fly. They put on new cloud services or solutions rather than taking the time to assess and carefully construct the optimal option.

Despite the fast use of cloud computing, many cloud ventures fail due to inadequate planning. According to IDC research, just 11% of businesses have maximized their cloud deployment.

This is why, prior to execution, you must explicitly define the scope of your multi-cloud approach. Your multi-cloud architecture should be built with a strategic eye toward discovering and prioritizing use cases that correspond with your business objectives. Taking a step back and designing from the ground up is often the best method.
