Cloud computing is the on-demand delivery of IT resources and applications via the Internet with pay-as-you-go pricing. On-demand self-service: Users can access cloud computing resources, such as virtual machines (VMs), storage, and applications, as needed and without requiring IT intervention.
Broad network access: Cloud resources can be accessed over the network, typically the Internet, using standard protocols such as HTTP and HTTPS.
Resource pooling: Cloud providers pool and share resources across multiple customers, using a multi-tenant model. This means that customers do not have their own dedicated resources but instead share resources that are allocated dynamically as needed.
Rapid elasticity: Cloud resources can be quickly and easily scaled up or down to meet changing demands.
Pay-as-you-go pricing: With cloud computing, customers only pay for the resources they use, when they use them. There is no need to make upfront investments in hardware or overprovision for peak demand.
Cloud computing offers many advantages over traditional on-premises IT infrastructure. These advantages can be summarized as follows:
Cost savings: With cloud computing, you only pay for the resources you use. There is no need to make upfront investments in hardware or overprovision for peak demand.
Flexibility: Cloud resources can be quickly and easily scaled up or down to meet changing demands.
agility: Cloud computing can help you quickly launch new applications and services, without the need to procure and provision new hardware.
Improved security: Cloud providers invest heavily in security and have teams of experts dedicated to keeping data safe.
Cloud computing certifications are professional credentials that demonstrate an individual’s expertise in designing, deploying and managing applications and infrastructure in the cloud. There are many different cloud computing certifications available, from entry-level to expert-level.
Cloud computing certifications can be divided into three broad categories:
Infrastructure as a Service (IaaS): These certifications focus on the design and deployment of cloud infrastructure, such as storage, networking, and virtualization.
Platform as a Service (PaaS): These certifications focus on the design and deployment of cloud-based applications and services.
Software as a Service (SaaS): These certifications focus on the design and deployment of cloud-based software applications.
Some of the most popular cloud computing certifications include:
AWS Certified Solutions Architect – Associate: This entry-level certification demonstrates an individual’s ability to design and deploy scalable, fault-tolerant, and highly available systems on the AWS platform.
AWS Certified SysOps Administrator – Associate: This entry-level certification demonstrates an individual’s ability to deploy, manage, and operate scalable, highly available, and fault-tolerant systems on the AWS platform.
AWS Certified Developer – Associate: This certification demonstrates an individual’s ability to develop and maintain applications on the AWS platform.
AWS Certified Solutions Architect – Professional: This expert-level certification demonstrates an individual’s ability to design and deploy scalable, fault-tolerant, and highly available systems on the AWS platform.
AWS Certified DevOps Engineer – Professional: This expert-level certification demonstrates an individual’s ability to design and implement a continuous delivery pipeline on the AWS platform.
CCNP Cloud: This certification demonstrates an individual’s ability to design, deploy, and operate Cisco cloud solutions.
CCIE Cloud: This expert-level certification demonstrates an individual’s ability to design, deploy, and operate Cisco cloud solutions.
VMware Certified Professional – Cloud: This certification demonstrates an individual’s ability to design and deploy VMware vSphere-based cloud solutions.
Prices for cloud computing certifications vary depending on the certification you choose and the provider you choose to take the certification from. However, you can expect to pay anywhere from $100 to $1,000 for a cloud computing certification.
Overall, cloud computing certifications are a great way to demonstrate your expertise in designing, deploying, and managing applications and infrastructure in the cloud. They can also lead to cost savings, increased flexibility, and improved security.
