What is cloud computing?
Instead of the hard drive of your device, cloud storage stores or accesses applications, software, and data via the internet. Software as a Service (SaaS), Application as a Service (PaaS), and Infrastructure as a Service (IaaS) is the most common examples of cloud computing, most of which you can opt to set up in a public or private environment.
The underlying architecture of infrastructure can take different forms and characteristics, including:
- Identified by software
Cloud Networking examples and use cases
There are some very clear cloud computing examples, many of which you might already be using in your personal or professional life:
- Options for document sharing, such as Dropbox, Google Docs, and Microsoft 365
- Telecommunication and social networking sites, such as Facebook, Twitter, and Skype
- CRMs and instruments for managing output, such as Salesforce and Atlassian
- Streaming web sites like Netflix, Sling, and Hulu
- Machine learning and the study of big data
- the IoT
A variety of classifications, styles, and design models span the word cloud computing. This networked computing paradigm has modified the way we run, and you are actually still using the cloud. But the cloud is not one thing; it is possible to categorize cloud computing into three general types:
- Public cloud is distributed over the internet and spread through organizations.
- Private cloud is cloud storage committed to the company alone.
- Any environment that incorporates both public and private clouds is a hybrid cloud.
Public vs Private vs Hybrid cloud: Quick Glance
|Public Cloud||Private Cloud||Hybrid Cloud|
|Reduced complexity||Customizable||Minimal security
|Agile for innovation||Efficient||Improved security|
What is the public cloud?
The public cloud refers to the model of cloud infrastructure in which internet distribution of IT services is supported. As the most common paradigm of cloud infrastructure services, in terms of solutions and computing capabilities, the public cloud provides large choices to meet the increasing needs of enterprises of all sizes and verticals.
Public cloud providers can be free, paid, or subscription-based, where you are charged based on the money you consume for storage.
The computing functionality can differ from typical resources to the enterprise-grade OS platform or infrastructure environments used for product creation and testing, from email, applications, and storage. It is the responsibility of the cloud provider to build, administer and retain the pool of computing services pooled across the network amongst multiple tenants.
When to use the public cloud
For these kinds of settings, the public cloud is more appropriate:
1. Predictable requirements for computation, such as communication services for a particular number of users
2. Apps and facilities available for carrying out IT and company operations
3. Additional specifications for services to meet differing peak demands
4. Development and testing environments for applications
Public Cloud Benefits
- No investment in the implementation and management of IT infrastructure is needed.
- High scalability and durability to fulfill unpredictable demands for workloads.
- The reduced complexities and specifications for in-house IT skills are diminished since technology maintenance is the responsibility of the cloud provider.
- The cost agility helps companies to adopt lean development plans and direct their efforts on innovation initiatives.
Public Cloud Pitfalls
- For large-scale use, especially for medium-sized to large companies, the total cost of ownership (TCO) can increase exponentially.
- The public cloud is the least stable, so it’s not best for mission-critical IT workloads that are vulnerable.
- Low infrastructure visibility and control could not fulfill your enforcement needs.
What is the private cloud?
The private cloud refers to any cloud solution that is allocated to a particular entity for use. You do not exchange cloud computing services with any other company on the private cloud. The infrastructure of the data center can be situated on-premises or operated off-site by a third-party provider. Computing services are segregated and delivered through a secure private network, and not shared with other customers
The private cloud is flexible to suit the organization’s specific business and security needs. Organizations can run compliance-sensitive IT workloads with improved visibility and control over the networks without losing the protection and efficiency previously experienced only with dedicated on-site data centers.
When to use the private cloud
- Highly managed sectors and government departments
- Critical Data
- Companies that need close control and protection over their IT workloads and the infrastructure underlying them
- Large organizations that need sophisticated data center technology to perform efficiently and cost-effectively
- Organizations that can continue to invest in technology with high efficiency and availability
Advantages of private cloud
- Exclusive environments. Dedicated and safe environments that other organizations cannot enter.
- Protection custom. Compliance with strict legislation, as companies can run security protocols based on the specific workload
- Without trade-offs, scalability. High scalability and reliability without losing security and performance to satisfy volatile requirements
- Effective performance. For high SLA performance and productivity, the private cloud is secure.
- Flexibility. When you transform the technology depending on the organization’s ever-changing market and IT requirements, the private cloud is scalable.
Drawbacks of private cloud
- When compared to public cloud equivalents, the private cloud is an expensive option with a comparatively high TCO.
- Mobile struggles. Considering the high-security controls, smartphone devices could have restricted access to the private cloud.
- Based on scalability. If the cloud data center is limited to on-premise computing, the system cannot provide high scalability to satisfy volatile requirements.
What is a hybrid cloud?
Any cloud infrastructure environment which incorporates both public and private cloud solutions is the hybrid cloud.
As an interconnected technology environment, the services are usually coordinated. Apps and data workloads, depending on corporate business and technology policy, will share resources between public and private cloud implementation around aspects such as:
This is a popular hybrid cloud example: companies will use private cloud environments to handle intermittent increases in network traffic for their IT workloads and supplement the infrastructure with public cloud tools.
When to use the hybrid cloud
- Organizations serving multiple verticals with various criteria for IT stability, regulations, and efficiency
- Optimizing infrastructure investments without compromising on the benefit that public or private cloud technology can offer
- Improving the security of current cloud solutions such as SaaS offerings that need to be distributed across secure private networks
Advantages of hybrid cloud
- Option-driven by the policy. Flexible policy-driven implementation to spread workloads based on security, efficiency, and cost criteria through public and private infrastructure environments.
- Scale with security. The scalability of distributed cloud architectures is accomplished without revealing the inherent vulnerability threats of critical IT workloads.
- Distributing resources through several data centers results in optimum reliability, some public, some private.
- Controlling costs. Improved security posture as dedicated private cloud services run on critical IT workloads while standard workloads are distributed through cheap public cloud networks to trade-off cost investments
Drawbacks of hybrid cloud
- It can be hard to trace swapping between private and public, resulting in unnecessary spending.
- Cloud technology covering various locations and categories requires good compatibility and convergence. This is a restraint on distributed cloud deployments, over which companies lack direct technology control.
- Complexity was introduced. When companies run and maintain an emerging combination of private and public cloud architecture, increased technology complexity is added.
Which cloud to choose?
Several variables, use cases, and constraints depend on the preference between public, corporate, and hybrid cloud solutions. This is rarely an either/or scenario in the real world, particularly when companies tend to exploit all three types of cloud technologies for the intrinsic value propositions of each one. But many organizations fail to understand what is the best kind of technology that they should use. If you are facing this kind of issue, we welcome you to join hands with us.
