Cloud computing is a rapidly growing field, with a projected market value of $800 billion by 2025. This course will discuss the fundamentals of cloud computing, including deployment models and service models, and will cover the benefits and advantages of cloud-based solutions compared to on-premise systems. The course will then focus on the two most popular cloud providers, AWS and Azure, explaining their respective services, features, and benefits.
Introduction to Cloud Computing
• 00:00:24 Cloud computing is the delivery of services, such as storage, computing power, and networking, over the internet. This technology allows businesses to scale quickly and efficiently. This course will cover essential topics such as introduction to cloud computing, steps to becoming a cloud engineer, cloud security, a comparison of AWS and Azure, and project ideas and certifications to boost your cloud computing journey.
Cloud Computing Benefits
• 00:03:56 Cloud computing offers several benefits compared to on-premise systems, including scalability, cost efficiency, improved security, and reduced maintenance. Cloud computing allows businesses to pay only for the services they use, enabling them to scale up or down quickly based on their needs.
Deployment Models
• 00:04:20 There are three main deployment models for cloud computing: public, private, and hybrid. Public clouds offer services to the public over the internet, while private clouds are exclusively operated by a single organization. Hybrid clouds combine the functionalities of both public and private clouds.
Service Models
• 00:05:12 Cloud computing also has three main service models: IaaS (Infrastructure as a Service), PaaS (Platform as a Service), and SaaS (Software as a Service). IaaS provides basic computing infrastructure, PaaS offers platforms and runtime environments for developing and managing applications, and SaaS hosts and manages software applications for users.
Amazon Web Services (AWS)
• 00:07:51 AWS is one of the leading cloud computing platforms, offering a wide range of services across various domains, including compute, storage, database, networking, analytics, machine learning, and more. AWS uses a pay-as-you-go pricing model, allowing users to pay only for the services they use.
AWS Use Cases
• 00:09:41 AWS provides services that support the entire application development process, from development, deployment, and running to scaling. For example, AWS offers compute services such as EC2, AWS Lambda, Amazon Lightsail, and Elastic Beanstalk for running applications. AWS also provides storage services such as Amazon S3, EBS, S3 Glacier, and Elastic File Storage for storing website data and user data in databases, enabling optimization and management.
Benefits of Using AWS
• 00:11:56 Companies like Netflix, Twitch, LinkedIn, Facebook, and BBC have successfully used AWS to improve business efficiency and scalability. AWS professionals are in high demand due to the widespread use of the platform, earning high salaries up to $127,000 per annum.
What is Azure?
• 01:09:10 Azure is a cloud computing platform provided by Microsoft, offering a range of services, including compute, storage, networking, and analytics. Azure is both a PaaS and IaaS, offering a wide range of programming languages and tools for developers.
Azure Use Cases
• 01:15:31 Azure offers services for various use cases, including application development, testing, hosting, virtual machine creation, data migration, mobile application development, and more.
Advantages of Azure
• 01:17:54 Azure offers a pay-per-use pricing model, a gentle learning curve, and a wide range of services across different domains. It also integrates well with on-premises systems, making it suitable for hybrid environments. Moreover, Azure is used by many large companies, including Pixar, Boeing, Samsung, EasyJet, Xerox, BMW, and 3M.
Cloud Security
• 02:10:09 Cloud security is essential for protecting businesses from threats both inside and outside the organization. It involves using various tools and practices to keep data safe, ensure only authorized users can access it, and protect it from potential threats. Examples of cloud security practices include encryption, strong passwords, multi-factor authentication, and regular software updates.
