As Cloud computing continues to permeate every aspect of our daily life and business, more businesses now demand dynamic IT solutions that take advantage of the associated benefits of improved agility and lowered costs.
However, the need to reorganise and re-evaluate unique solutions and architecture to meet the changing business goals and needs can be very complex. Managing hundreds or even thousands of different applications written by different people, in different languages and at different times requires meticulous planning, oversight and insight. This makes the critical decision of which environment between public cloud and private cloud to deploy your applications and services all the more important.
What is Private Cloud?
Also referred to as an enterprise or internal cloud, a private cloud is a cloud solution dedicated for use by only one organisation and delivered through a secure private network. The data centre resources can be located on-premise or hosted off-site by a third-party vendor. This gives you more control and visibility into the infrastructure thereby allowing you to customise the private cloud to meet your unique business and security needs.
Advantages of Private Cloud
- Dedicated secure environments that can only be accessed by one organisation
- Ability to run unique configurations, measures, protocols and also customise security, based on workload requirements thereby complying with strict regulations
- High SLA efficiency and performance
- High efficiency and scalability to meet fluctuating demands without compromising on performance or security
- Ability to adapt the infrastructure based on changing organisational IT and business needs.
Limitations of Private Cloud
- Can be significantly more expensive than the public cloud solution with a high total cost of ownership.
- If the cloud data centre is limited to on-premise computing resources, the infrastructure may not be sufficiently scalable to meet unpredictable demands
- Considering the high-security measures in place, mobile users may have limited access to the private cloud.
When to Use the Private Cloud
The private cloud is ideal in the following scenarios;
- Technology companies requiring strong security and control of the underlying infrastructure and their IT workloads
- Highly regulated government agencies and industries
- Large enterprises requiring advanced data centre technologies to operate cost-effectively and efficiently.
- Big organisations that can afford to invest in availability and high-performance technologies.
What is Public Cloud?
The public cloud refers to a cloud computing model in which IT services are hosted and maintained by an external provider then shred between multiple tenants across the network. Examples include Microsoft Azure and Amazon AWS. The computing functionality may range from common services such as apps, email and storage to enterprise-grade infrastructure environments or OS platforms for software testing and development. The stand-out feature of the public cloud solution is its high scalability and elasticity for delivering low-cost subscription-based services.
Advantages of Public Cloud
- High flexibility and scalability to meet fluctuating workload demands
- Flexible pricing options
- Reduced complexity and the need to have in house IT expertise. The vendor manages the infrastructure.
- No investment required to deploy or maintain the IT infrastructure
- Flexible pricing allows organisations to only pay for the services they need and to follow lean growth strategies.
Limitations of Public Cloud
- For large scale use in midsize and large enterprises, the total cost of ownership can rise exponentially.
- Low control and visibility into the infrastructure may not be enough to comply with all regulations.
- May not be ideal for availability and security-sensitive mission-critical IT applications
When to Use the Public Cloud
The public cloud is ideal for situations with these needs;
- Apps and services necessary to perform business and IT operations
- Software development and test environments
- Predictable computing needs such as communication services for a defined number of users
- Additional resource requirements to address changing resource demands
Which Type of Cloud Should you Choose?
The choice between public and private cloud solutions depends on many different factors, limitations and use cases. In practice, it is not an either/or question as different businesses have different needs and considerations.
Azure On-Premise vs. Cloud
If you are considering migrating your applications into Microsoft Azure cloud platform, this is a case in point. Both solutions have unique strengths and downsides depending on your business needs and the services you are setting up. For this reason, the decision can be incredibly complex. Therefore, taking the time to fully understand the costs associated with both cloud and on-premise Azure solutions and formulating a holistic cloud strategy will help you arrive at the right solution uniquely suitable for your organization into the future.
