Module 2 notes: Think about: · What goes into a decision to deploy to the cloud? · What different cloud services are available? · What deployment models are available? · Is the cloud right for everyone? In this module, you will learn more about making an informed decision about using cloud computing services. The following questions are key to making those decisions: · Do you have on-premise servers for processing and storing data? · Have you assessed your organization's readiness? · Have you considered which deployment model is right for your organization? · Have you considered which services model(s) your organization may leverage? Discussion post: discuss the differences between public cloud service delivery models and on-premise models. How do these differences affect how your data is gathered and manipulated? Are there cost, security, or regulatory considerations? Big Data, Big Analytics textbook: Abhistek Mehta said that his clients are saying they do not have unlimited resources to invest in the infrastructure needed to store data. Using your own servers is a capital-intensive infrastructure cost for storing data. Cloud model: pay as a subscription, no upfront capital expense/cost, updates are automatic, and don't have the typical 30% maintenance fees, massively scalable platform- add products and services for zero additional cost, "To master analytics, enterprises will move from being in reactive positions (business intelligence) to forward leaning positions (predictive analytics)."
Software as a Service(Saas) The basic principle of SaaS is to help companies get solutions without needing to build and maintain their onsite implementation. Benefits of SaaS: -immediate access to talnet Open-source stack- flexibility, extensibility, and lower cost Reading: How to Calculate Cloud Migration Costs Before You Move opens in new window Capex vs. Opex To evaluate the cost of moving to the cloud, start by comparing the upfront charges for on-premises resources against the annual fees for per-use cloud consumption. $1k $1k $1k $1k $10k $1k $1k $1k $1k $1k $1k Upfront investment, 10-year life span As-a-service annual costs, 10 years 82021 TOCHTARGET.

Cloud service prices also vary depending on whether you reserve the resources ahead of time or consume them as you go. Cloud cost calculators The best way to calculate cloud costs is to use a calculator tool designed for this purpose. All the major cloud vendors have their own calculators, such as: · AWS Pricing Calculator · Microsoft Azure Pricing Calculator · Google Cloud Pricing Calculator Third-party calculator: Apptio Cloudability Possible cloud migration costs: -massive data migrations may require a special service as network may not be strong enough -labor IT may not have the skills. May need to outsource the labor. -consulting May hire a consulting company if the cloud is not part of your expertise -backup you should use a second cloud or an on-premises data storage as backup data
