What is the relation of a Main Frame to Terminals
In early days of computers, there was a Main Frame which held data, that was able to be accessed by terminals (dumb terminals)
What is a hypervisor?
Hypervisors allow a single set of physical hardware to host multiple virtual machines, and hold all of the necessary variables and information required to make those virtual machines work.
List the 6 Advantages of Cloud Computing
- Trade capital expense for variable expense
- Benefit from massive economies of scale
- Stop guessing capacity
- Increase speed and agility
- Stop spending money running and maintaining data centers.
- Go global in minutes
Name the types of Cloud Computing Models
- Infrastructure as a Service (IaaS)
- Platform as a Service (PaaS)
- Software as a Service (SaaS)
Describe Infrastructure as a Service
- Basic building blocks
- Provides most flexibility and management control
- Closes to having traditional on-premise data center
- AWS, Azure, Google Cloud
Describe Platform as a Service
- Deploy and manage applications without worry
- Execute programming languages to host applications
- Azure web hosting, Heroku, Google app engine
- Less flexibility than IaaS as packages are preconstructed
Describe Software as a Service
- Completed products managed by the service provider
- Easy to use as end user
- Least flexibility
- Outlook/Gmail (Send and receive email, nothing else)
Name the Cloud Deployment models
- Cloud Deployment
- On-premises/Private Cloud Deployment
- Hybrid Cloud Deployment
List details of a Cloud Deployment
- Least amount of IT resources needed
- 100% of the IT infrastructure on the cloud
- All applications migrated to or created in the cloud
- Removes roadblock of costly and time-consuming procurement processes
List details of an On-premise/Private Cloud Deployment
- For organizations that need all secured data available locally
- Use virtualization to deploy resources in their on-premises data centers
- Often looks like traditional IT infrastructure, with servers, data cables etc
- Access quickly because nothing is downloaded
- Resources cannot be accessed using the internet
- Security: Provides dedicated resources
List details of a Hybrid Cloud Deployment
- Typically organizations with on premises resources already established
- Connects on-premises technology with cloud-based resources
- Great for established companies that are in the process of migrating over to the cloud
- Data partially on the cloud and partially in the on-premises data center
- Can use as backup and disaster recovery solution
List 5 pillars of a well architected framework
- Build the most secure, durable, efficient, and high-performing IT infrastructure possible -
5 Best Practices - Avoid unnecessary costs: use what you need, reserve resources in advance, continue to monitor for optmization
- Reliability - Disaster recovery settings and options, incorporate redundancy, duplicate copies of resources
- Efficiency
- Security - Information, systems, and assets, should be secure. Best practices should be automated, data should be protected when stored and when in transit, enable traceability, Manage access
- Operational Excellence - Monitor and maintain services while constantly improving processes and procedures - Document everything, refine, operational procedures, anticipate failure, update processes
List the 3 cloud computing deployments
- Public cloud
- Hybrid cloud
- Private cloud (On-prem cloud)
What are compute services?
- Virtual server hosting, container management, server less computing
No longer purchase or maintain physical servers to host their own services, rent server compute space and capacities for cheap
What are storage services?
- Provide storage for both in-use and archival files
- Different costs associated with how often you need to access files and how durable or available you want them to be
- Storage type for almost every level of need with granular costs to meet budget requirements
What are Database Services?
- Fully managed relational and NoSQL databases
- Fully managed scalable petabyte-scale data warehouse service
- Highly scalable and cost efficient, fraction of the cost of on-site database servers
What is Amazon Web Services?
- Provides IT infrastructure services to orgs as web services
- Resources are accessed using the internet
- Pay as you go model to help orgs
- Service provider that offers flexibility, reliability and affordability
