What is Cloud computing ?
Cloud computing refers to the delivery of computing resources and services, including servers, storage, databases, networking, software, and analytics, over the internet. Rather than maintaining their own computing infrastructure or data centers, businesses and individuals can access these services on-demand from a cloud service provider.
In more concrete terms, cloud services are things like Amazon Elastic Compute
Cloud (EC2) or Google Compute Engine (GCE), which provide APIs to provision
virtual servers, where customers pay per hour for the use of these servers.
In many ways, cloud is the next layer of abstraction in computer infrastructure, where computing, storage, analytics, networking, and more are all pushed higher up the computing stack. This structure takes the focus of the developer away from CPUs and RAM and toward APIs for higher-level operations such as storing or querying for data. Cloud services aim to solve your problem, not give you low-level tools for you to do so on your own.
Further, cloud services are extremely flexible, with most requiring no provisioning or long-term contracts. Due to this, relying on these services allows you to scale up and down with no advanced notice or provisioning, while paying only for the resources you use in a given month
Cloud computing types
Cloud computing can be divided into three main types:
- Public cloud: Public cloud refers to cloud services that are available to the public. These services are provided by a third-party cloud service provider, and users can access them over the internet. Public cloud services are typically designed for general use and can be accessed by anyone with an internet connection.
- Private cloud: Private cloud refers to cloud services that are used exclusively by a single organization. Private cloud services are typically hosted on-premise or in a dedicated data center and are designed to provide enhanced security and control over resources.
- Hybrid cloud: Hybrid cloud refers to a combination of public and private cloud services. Hybrid cloud allows organizations to use both public and private cloud services, depending on their specific needs. For example, an organization may use public cloud services for non-sensitive workloads and private cloud services for sensitive workloads that require enhanced security and control.
What is Google Cloud Platform ?
Google Cloud Platform (GCP) is a cloud computing platform provided by Google that allows individuals and organizations to build, deploy, and manage various types of applications, websites, and services in a secure and scalable manner. It provides a range of services such as compute, storage, networking, databases, machine learning, and more, which can be used individually or in combination to meet various computing needs. GCP also provides tools and services for managing and monitoring applications, as well as for analyzing data and gaining insights. Users can access and manage GCP services through a web console, command-line interface, or API.
Why cloud ?
Cloud computing offers numerous benefits that make it an attractive option for individuals and organizations alike. Here are some reasons why:
- Scalability: Cloud computing allows users to quickly and easily scale up or down their computing resources based on their changing needs, without having to invest in and maintain physical hardware.
- Cost efficiency: Since users only pay for what they use, cloud computing can be more cost-effective than investing in and maintaining physical hardware.
- Accessibility: Cloud computing allows users to access their computing resources from anywhere with an internet connection, making it easier to work remotely or collaborate with others
- Security: Cloud computing providers invest heavily in security measures to protect users’ data, which can be more secure than storing data on physical hardware.
- Flexibility: Cloud computing allows users to choose from a wide range of computing services and tools, making it easier to find and use the services that best meet their needs.
Why not cloud ?
While cloud computing offers many benefits, there are also some potential drawbacks that should be considered:
- Reliance on internet connectivity: Cloud computing requires a reliable internet connection, which can be a problem if the connection is slow or unreliable.
- Security concerns: While cloud computing providers invest heavily in security measures, there is always a risk that data stored in the cloud could be compromised.
- Limited control: With cloud computing, users have less control over the underlying infrastructure and may not be able to customize it to their specific needs.
- Potential vendor lock-in: Once an organization has invested heavily in a particular cloud computing provider, it can be difficult to switch to another provider or move back to traditional computing methods.
- Dependency on third-party providers: When using cloud computing, users are relying on the services and infrastructure provided by third-party providers, which can be a concern if the provider experiences downtime or goes out of business.
What to expect from cloud services ?
Cloud services provide a range of benefits to individuals and businesses, such as increased flexibility, scalability, and cost savings. Here are some of the things you can expect from cloud services:
- Access to resources anytime, anywhere: With cloud services, you can access your data, applications, and resources from anywhere with an internet connection. This means you can work remotely, collaborate with others easily, and be more productive.
- Scalability: Cloud services can scale up or down quickly based on your needs. You can easily add or remove resources as your workload changes, which can save you money and help you avoid downtime.
- Cost savings: Cloud services can be more cost-effective than traditional on-premise solutions because you only pay for the resources you use. There’s no need to purchase expensive hardware or software upfront, and you can avoid maintenance and upgrade costs.
- Security: Cloud service providers often have advanced security measures in place to protect your data from threats like cyber attacks and data breaches. This can be especially important for businesses that handle sensitive data
- Automatic backups and disaster recovery: Cloud services can automatically backup your data and provide disaster recovery options in case of a data loss event. This means you can be confident that your data is safe and can be quickly restored if needed.
- Integration with other services: Many cloud services can easily integrate with other services you may use, such as productivity tools, customer relationship management (CRM) systems, and more.
What is a cloud application ?
A cloud application, also known as a web application or Software as a Service (SaaS), is an application that is hosted and operated by a cloud service provider and accessed through a web browser or a dedicated application.
Cloud applications are designed to be flexible and scalable, allowing users to access them from anywhere with an internet connection. They often offer a subscription-based model, where users pay a recurring fee for access to the application and the resources it requires.
Cloud applications can be used for a wide range of purposes, such as collaboration, project management, customer relationship management, and more. They can also be customized and integrated with other cloud services, allowing for a seamless workflow across multiple applications.
Some examples of popular cloud applications include Google Drive, Dropbox, Salesforce, Slack, and Microsoft 365. Cloud applications offer many benefits over traditional on-premise software, including lower costs, automatic updates, and easy collaboration.
