Cloud Computing..What is it? and what does it mean?
- 1. Use ful for beginers Cloud Computing .. What is it? And what dose it mean?
- 2. WHAT IS CLOUD COMPUTING? • Cloud computing is an information technology paradigm that enables ubiquitous access to shared pools of configurable system resources • higher-level services that can be rapidly provisioned with minimal management effort, often over the Internet.
- 4. TYPES • SaaS (software as a service) • IaaS (infrastructure as a service) • PaaS (platform as a service) • FaaS (functions as a service) • Private cloud • Hybrid cloud • Public APIs (application programming interfaces) • iPaaS (integration platform as a service) • IDaaS (identity as a service) • Collaboration platforms • Vertical clouds
- 5. SAAS • This type of public cloud computing delivers applications over the internet through the browser. • Typically, SaaS applications offer extensive configuration options as well as development environments • That enable customers to code their own modifications and additions.
- 6. IAAS • At a basic level, IaaS public cloud providers offer storage and compute services on a pay-per-use basis. • But the full array of services offered by all major public cloud providers is staggering. • Highly scalable databases, virtual private networks, big data analytics, developer tools, machine learning, application monitoring, and so on.
- 7. PAAS • PaaS provides sets of services and workflows that specifically target developers and APIs to accelerate the development, test, and deployment of applications. • Note that a variety of PaaS tailored for developers of mobile applications generally goes by the name of MBaaS (mobile back end as a service), or sometimes just BaaS (back end as a service).
- 8. FAAS • FaaS, the cloud instantiation of adds another layer of abstraction to PaaS. • so that developers are completely insulated from everything in the stack below their code • All the major clouds offer FaaS on top of IaaS: AWS Lambda, Azure Functions, Google Cloud Functions, and IBM OpenWhisk. • A special benefit of FaaS applications is that they consume no IaaS resources until an event occurs, reducing pay-per-use fees.
- 9. PRIVATE CLOUD • The private cloud downsizes the technologies used to run IaaS public clouds into software that can be deployed and operated in a customer’s data center. • VMware’s Software Defined Data Center stack is the most popular commercial private cloud software, while OpenStack is the open source leader.
- 10. HYBRID CLOUD • A hybrid cloud is the integration of a private cloud with a public cloud. • The hybrid cloud involves creating parallel environments in which applications can move easily between private and public clouds. • The types of integrations between private and public cloud vary widely, but they must be extensive to earn a hybrid cloud designation.
- 11. PUBLIC API’S • Just as SaaS delivers applications to users over the internet, public APIs offer developers application functionality that can be accessed programmatically. • For example, in building web applications, developers often tap into Google Maps’ API to provide driving directions; • To integrate with social media, developers may call upon APIs maintained by Twitter, Facebook, or LinkedIn.
- 12. IPAAS • Data integration is a key issue for any sizeable company, but particularly for those that adopt SaaS at scale. • iPaaS providers typically offer prebuilt connectors for sharing data among popular SaaS applications • on-premises enterprise applications, though providers may focus more or less on B-to-B and ecommerce integrations, cloud integrations, or traditional SOA-style integrations.
- 13. IDAAS • The most difficult security issue related to cloud computing is the management of user identity and its associated rights and permissions across private data centers and pubic cloud sites • IDaaS providers maintain cloud-based user profiles that authenticate users • Enable access to resources or applications based on security policies, user groups, and individual privileges.
- 14. COLLABORATION PLATFORMS • Collaboration solutions such as Slack, Microsoft Teams, and Hip Chat have become vital messaging platforms that enable groups to communicate and work together effectively. • Basically, these solutions are relatively simple SaaS applications that support chat-style messaging along with file sharing and audio or video communication.
- 15. VERTICAL CLOUDS • Key players in such industries as financial services, healthcare, retail, life sciences, and manufacturing • Provide PaaS clouds to enable customers to build vertical applications that tap into industry-specific, API-accessible services • Most vertical clouds are built with the intent of nurturing partner ecosystems.
- 16. ADVANTAGES • The cloud’s main appeal is to reduce the time to market of applications that need to scale dynamically. • Although businesses sometimes migrate legacy applications to the cloud to reduce data center resource requirements. • The real benefits accrue to new applications that take advantage of cloud services and “cloud native” attributes
