IBM cloud

 IBM Cloud

IBM cloud computing is a set of cloud computing services for business offered by the information technology company IBM. IBM cloud includes infrastructure as a service (IaaS), software as a service (SaaS) and platform as a service (PaaS) offered through public, private and hybrid cloud delivery models, in addition to the components that make up those clouds.

IBM offers three hardware platforms for cloud computing. 

 These platforms offer built-in support for virtualization. For virtualization IBM offers IBM Websphere application infrastructure solutions that support programming models and open standards for virtualization.
The management layer of the IBM cloud framework includes IBM Tivoli middleware.
Management tools provide capabilities to regulate images with automated provisioning and de-provisioning, monitor operations and meter usage while tracking costs and allocating billing. The last layer of the framework provides integrated workload tools.
Workloads for cloud computing are services or instances of code that can be executed to meet specific business needs.
IBM offers tools for cloud based collaboration, development and test, application development, analytics, business-to-business integration, and security

 IBM Cloud refers to a collection of enterprise-class technologies and services developed to help customers assess their cloud readiness, develop adoption strategies and identify business entry points for a cloud environment. IBM's cloud computing strategy is based on a hybrid cloud model that focuses on integrating the private cloud services of a company with the public cloud.

Public, private and hybrid cloud models

IBM offers cloud delivery options including solely private cloud, solely public cloud, and variations in between. Private, public and hybrid clouds are not strictly distinct, as IBM allows the option to build a customized cloud solution out of a combination of public cloud and private cloud elements. Companies that prefer to keep all data and processes behind their own firewall can use private cloud services managed by their own IT staff. A company may also choose pay-as-you-go pricing. Hybrid cloud options allow for some processes to be hosted and managed by IBM, while others are kept on a private cloud or on a VPN or VLAN. IBM also offers planning and consultation throughout the deployment process. IBM offers five cloud provision models:
  • Private cloud, owned and operated by the customer
  • Private cloud, owned by the customer, but operated by IBM (or another provider)
  • Private cloud, owned and operated by IBM (or another provider)
  • Virtual private cloud services (based on multi-tenanted support for individual enterprises)
  • Public cloud services (based on the provision of functions to individuals)

IBM Cloud Services

Because IBM seems to be focusing more attention on Bluemix than SoftLayer, this list will cover its Bluemix offerings rather than those available through SoftLayer. The company divides its Bluemix Services into twelve categories:
  • Compute Infrastructure — includes its bare metal servers (single-tenant servers that are highly customizable), virtual servers, GPU computing, POWER servers (based on IBM's POWER architecture) and server software
  • Network — includes load balancing, Direct Link private secure connections, network appliances, content delivery network and domain services
  • Compute Services — includes OpenWhisk serverless computing, containers and Cloud Foundry runtimes
  • Storage — includes object, block and file storage, as well as server-backup capabilities
  • Mobile — includes IBM's Swift tools for creating iOS apps, its MobileFirst Starter package for getting a mobile app up and running, and its Mobile Foundation app back-end services
  • Data and analytics — includes data services, analytics services, big data hosting, Cloudera hosting, MongoDB hosting and Riak hosting
  • Watson — includes IBM's artificial intelligence and machine learning services, which it calls "cognitive computing," such as Discovery search and content analytics, Conversation natural language services and speech-to-text
  • Internet of Things — includes IBM's IoT platform and its IoT starter packages
  • Security — includes tools for securing cloud environments, such as a firewall, hardware security modules (physical devices with key management capabilities), Intel Trusted Execution Technology, security software and SSL certificates
  • Integration — includes tools for building virtual bridges for hybrid cloud and multi-cloud environments, such as API Connect and Secure Gateway
  • DevOps — includes the Eclipse IDE, continuous delivery tools and availability monitoring
  • Application services — includes Blockchain, Message hub and business rules, among others
