Which 'aaS' is Right for You?

  1. 1. Which “aaS” is Right for You?
  2. 2. Cloud Computing • Cloud computing is a very broad term that encompasses anything from Facebook to Twitter to Google Apps to Amazon’s S3 • When considering cloud computing, it’s important to decide what kind of cloud you’re talking about • Each “aaS” (careful how you pronounce that) is very different so you need to understand which is right for you
  3. 3. SaaS • SaaS (Software-as-a-Service) provides network-based access and management of software in a centralized location that can be accessed remotely via the web • Allows for frequent integration into a larger network of software • One-to-many model • Example: Google Apps
  4. 4. SaaS • Main benefits: – Flexibility – Scalability • Criticisms: – Lack of personal control (systems are centrally controlled) – Need to alter business processes to fit the system – Security issues
  5. 5. PaaS • PaaS (Platform-as-a-Service) allows companies to rent hardware and software to build applications, rather than owning, running and developing on an internal IT infrastructure • Servers, operating systems and maintenance rolled all into one bill – Up to you to run and serve applications and data off the servers
  6. 6. PaaS • Features: – Application design & development – Testing – Deployment – Hosting – Collaboration • Example: force.com
  7. 7. IaaS • IaaS (Infrastructure-as-a-Service) is the base level of the cloud computing stack • Serves as a foundation for PaaS and SaaS in terms of execution • Cloud infrastructure (i.e. servers, routers, hardware, storage, etc.) is provided by an IaaS vendor • Never have to pay directly for any hardware • Example: Amazon’s EC2
  8. 8. SaaS vs. PaaS vs. IaaS • If you’re looking for: – Online networks to enhance collaboration, you need SaaS – System to support the entire lifecycle of your web applications, you need PaaS – Virtual place to host and manage your data, you need IaaS • Before implementing cloud services, identify your needs then figure out which “aaS” provides that
  9. 9. After Deploying Your “aaS”… • After deploying your “aaS” service, don’t forget to have a backup plan in case of any point of failure, accidental deletion, employee error, hack, or glitch in your system • Backupify provides both a social media and Google Apps backup solution
