1.8 Summarize cloud concepts and connectivity options

Infrastructure as code and Automation/orchestration

Infrastructure as Code (IaC) and Automation/Orchestration are two related concepts in cloud computing. IaC is a process where an organization can manage and automate the deployment and configuration of their infrastructure using code, rather than manual processes. Automation and orchestration are technologies that enable IaC and can help organizations manage their cloud infrastructure in a more efficient and scalable way.

Explain the following Connectivity options

Virtual private network (VPN) is a secure and encrypted connection between a device and a network over the Internet. It allows users to access the resources on a private network as if they were physically connected to the network, while still maintaining the security of the data being transmitted. VPNs use tunneling protocols to encrypt the data being transmitted and to create a secure connection between the device and the network.

Private-direct connection to cloud provider is a dedicated, high-bandwidth connection between an on-premises network and a cloud provider's network. This direct connection eliminates the need to transmit data over the public Internet and provides a secure and reliable connection with lower latency and jitter. This type of connection is useful for organizations that need to transfer large amounts of data to and from the cloud, or for those who require the lowest possible latency for cloud-based applications.

Multitenancy

Multitenancy refers to the ability of a single instance of a software application or hardware infrastructure to serve multiple customers, each with separate and isolated access to the application or infrastructure. This allows multiple tenants to share the same resources while still having their own individual data, customizations, and configurations.

Elasticity

Elasticity refers to the ability of a cloud-based system to dynamically allocate and deallocate resources based on demand. This allows the system to automatically scale up or down based on current usage, reducing costs and increasing efficiency.

Scalability

Scalability refers to the ability of a system to grow and accommodate increased demand over time. A scalable system can handle an increased workload without sacrificing performance or stability.

Security implications

Security implications refer to the potential risks and threats associated with using cloud services, such as unauthorized access to sensitive data, theft of confidential information, or attacks on cloud infrastructure. It is important for organizations to carefully consider the security implications of using cloud services and to implement appropriate security measures to protect their data and systems.
