Characteristics On demand service Use it as you needed 2. Network Access Uses internet as a medium 3. Share resources Resources are pooled together – Used by multiple clients

Cloud Computing Overview

Cloud Computing Overview 1890 - Power generator – When things work, it is great, when it doesn’t nothing get done 1900 Chicago – Edison power company developed a turbine power station – generate and distribute large scale power to business : Cheaper, more reliable and cleaner compare to any factory based generator.

Cloud Computing Overview By 1920 most of the business switched to Edison, in house power generator no longer make sense since virtually unlimited power is granted. 1920 – Most businesses have made a switch. Business now access power simply by plug into the wall. In house power generator no longer make sense. Today, we take virtually unlimited power for granted. We can’t imagine it any other ways https://www.youtube.com/watch?v=whkyRvugqlM&t=195s

IT Revolution IT has a similar revolution today. Business No longer has to buy build and manager costly computer facilities on site - More secure, more reliable and more scalable

Competitive Advantage High Speed & Low Cost 24/7 secure access on more business apps Traditional data facilities are struggling to keep up

Advantages Universal Access: Cloud computing services are platform independent; they are accessible across all devices with internet connection. This increases mobility and ensures that you can access all your information from any place. By this, cloud computing also increase productivity as it allows staff to collaborate on projects. More Storage Capacity: Cloud computing offers an unlimited storage as long as you can afford it. You don't have to worry about running out of storage and having to buy SSD hard disks for backups.

Advantages Cost Effective: As an on demand service, cloud computing is cheap. You only pay for what you use, and you don't incur the initial capital of acquiring the infrastructure. You don't also incur other costs such as maintenance, security, and storage costs. Some providers may offer cloud computing for free to their clients.

Advantages Easy and Quick Set-Up: Unlike On-Premise infrastructure, when using cloud, you don't need to install anything or worry about the underlying hardware. All you need is to connect to a network/Internet, register with a cloud provider and adjust some simple configurations and that's it. Automatic Updates: Cloud providers are responsible for their underlying infrastructure. You will not worry about acquiring an update, a new software, their licenses or upgrading some hardware. With cloud computing, all this solely done by the provider. Maybe you only need to download a client software update. 

Risks Security Risks As with all other technologies, cloud computing is susceptible to security vulnerabilities. Cloud providers's servers can be attacked given the fact that millions of people are accessing them hourly. Since cloud uses the Internet, Internet related risks such as malware, man in the middle attacks and eavesdropping can be experienced. Privacy Issues The CIA triad - confidentiality, integrity, and availability of information can be breached when using cloud computing. Your data can be accessed by unauthorized entities or even modified.

Risks Loss of Control Using some services of cloud computing means that you lose control over some entities. The entities dictate on how they'll be used since cloud uses the on-demand service model. And at times if the servers are down, you will have no option but to wait. Cloud Provider Reliability Since you don't have control over the cloud computing entities, you have to rely fully on the cloud provider. If anything happens to your cloud provider, you will also be affected. https://www.zdnet.com/article/amazon-web-service-suffers-network-failure-in-korea/ AWS (Amazon Web Service) South Asia Internal DNS issue – Server is down – Emergency check up - 4 main coin trader out of service

Risks Internet Reliance: If you don't have access to the Internet, well, you also lose access to the cloud. And yes there are places where Long Term Evolution and even the 3rd generation networks are not available.

Delivery models of Cloud Computing 1. SAAS – Software as a service 2. PAAS – Platform as a service 3. IAAS – Infrastructure as a service

Common use of cloud

SAAS – Software as a service On-Demand Service Pay per use of application software to users Independent platform Don’t need to install the software on your PC. Runs a single instance of the software Available for multiple end users. Accessible via a web browser or lightweight client applications Computing resources managed by vendor

Who uses SAAS? End consumer (End user)

SAAS PROS/CONS Pros Cons Universally accessible from any platform No need to commute, you can work from anywhere Excellent for collaborative working Vendor provides modest software tools Allows for multi-tenancy Cons Portability & Browser issues Internet performance may dictate overall performance Compliance restrictions

PAAS – Platform as a service A platform allowing customers to develop, run, and manage applications without the complexity of building and maintaining the infrastructure This model allows you to manager data & the application resources Open PaaS Standalone PaaS Addon PaaS Application delivery PaaS : All other resources are managed by the vendor

Who uses PAAS? Developer

PAAS PROS/CONS Pros Cons Cost effective rapid development (scalable). Faster market for developers. Easy deployment of web applications. Private or public deployment is possible. Cons Developers are limited to the providers' languages and tools. Migration issues – such as the risk of vendor lock-in.

IAAS – Infrastructure as a service Offers the computing architecture and infrastructure Offers all computing resources but in a virtual environment. Multiple user can access them. Most vendors are responsible for managing four resources: Virtualization Servers Networking Data Storage. If you will use this service, you will be responsible for handling other resources such as applications, data, runtime, and middleware.

Who uses IAAS? Mainly for System Administrator

IAAS PROS/CONS Pros Cons The Cloud provides the infrastructure. Enhanced scalability – dynamic workloads are supported. IaaS is flexible. Cons Security issues. Network and service delays.

AI and Cloud Computing Artificial Intelligence Machine Learning (vs Computer Science) Large number of data (Big Data) Infrastructure Accessibility of old and new data

AI and Cloud Computing AI & Cloud Emerging IBM states that the fusion of AI and cloud computing “promises to be both a source of innovation and a means to accelerate change.” The cloud can help provide AIs with the information which they need to learn, while the AI can provide information which can give a cloud more data

Cloud Computing Outlook Decrease in private company’s own data centers Escalate AI development in a rapid pace Reduce in IT man power Development of Enterprise (Package) Support small business’s innovation

Cloud Computing Outlook https://hackernoon.com/edge-computing-a-beginners-guide-8976b6886481

Cloud Computing Outlook Edge Computing Substitute of cloud computing Prevent bottleneck / sluggish process Use Edge (Smart devices) that is close to where data was created

Closing If you own a business, would you utilize the cloud service over to on premises server? What is a hybrid cloud? What is a multi cloud?
