Openstack, SaaS, PaaS, IaaS

TeraSky experts have a deep knowledge and experience in deployment of OpenStack – open, standard platform – when building massively scalable clouds for customers. OpenStack is a free and open-source software platform for cloud computing, mostly deployed as an infrastructure-as-a-service (IaaS). The software platform consists of interrelated components that control hardware pools of processing, storage, and networking resources throughout a data centre.

TeraSky offers its customers the unique capabilities in OpenStack deployment, service & support, based on development tools knowledge and skills brought from working for years with the leading vendors and open source software distributions (Linux, VMware, RHEV, KVM, Hyper-V, Acropolis, MS, Oracle, MS SQL, Etc.). As far as OpenStack mostly deployed as IaaS, TeraSky, in addition to the SW development skills, brings deep infrastructure building blocks knowledge (server virtualization solutions: KVM, RHEV, VMware; Software Defined Storage: RH GlusterFS, CEPH; Cloud Storage Software: SWIFT, CINDER, GLANCE; Traditional Storage Solutions: EMC, IBM, HPE, Infinidat, Nimble, etc.).

OpenStack is not a shelf product, but a framework and it can take from months to years to build something reasonable and integrate it with a current customer’s environment. A specialized knowledge is necessary to build and develop open source cloud infrastructure. The administrators have to ensure proper infrastructure operations, for which deep skills of solution administration and maintenance are mandatory. IT organizations who attempt to deal with OpenStack implementation complexity on their own by integrating all components from scratch and being up-to-date at all times, exposes themselves to the risk of creating their own, unmanageable solution.

TeraSky partners with OpenStack major contributors: Red Hat, HPE, IBM, CISCO, EMC, VMware. That gives us the opportunity to integrate the best and mature elements into our solutions. TeraSky leverages and assists the mentioned above contributors in making implementation more mature and efficient. Highly experienced TeraSky team provides a fast response and support to various technical challenges, as we work closely with OpenStack developer’s community.

TeraSky knowledge of Automation tools: VMware (vCAC/vRealize), Red Hat Cloudforms, Satellite helps our customers to integrate OpenStack with a traditional environments and build a reliable, agile and modern DC (on premises or cloud based – public, private or hybrid).

TeraSky professional services organization provides world-class support and subscription licenses when it is required.

Infrastructure as a Service (IaaS) is a form of cloud computing that provides virtualized computing resources over the Internet. IaaS is one of three main categories of cloud computing services, alongside Software as a Service (SaaS) and Platform as a Service (PaaS).

In an IaaS model, a third-party provider hosts hardware, software, servers, storage and other infrastructure components on behalf of its users. IaaS providers also host users’ applications and handle tasks including system maintenance, backup and resiliency planning.

Terasky specialist can assist you to decide which highly scalable resources that can be adjusted on-demand and discover the well-suited workloads to be moved to IaaS cloud model.

Terasky professional team has many years of experience in automation of administrative tasks, based on Vmware VCAC/V-realize, Red Hat Cloudforms and Satellite solutions, dynamic scaling, desktop virtualization and policy-based services, which will make the move to IaaS transparent.

Our team work on many en­gage­ments in­volving cloud com­puting, as al­ways bringing our spe­cial eye for aligning busi­ness needs with ap­pro­priate tech­nology and how to deliver strategic advantages to the business by redirecting resources from lights-on to innovation. It lets organizations:

  • Quickly bring new applications & services online for faster time-to-revenue
  • More quickly respond to opportunities and threats
  • Keep better balance between CAPEX and OPEX

TeraSky has a vast knowledge and skills in the basic Cloud Computing building blocks such as:

  • Software Defined Storage (GlusterFS, CEPH, SWIFT, CINDER, Etc.);
  • Systems Virtualization (VMware, RHEV, KVM, Etc.);
  • Automation (CloudForms, vCAC/vRealize, Etc.);
  • Hyperconverged Solutions (Nutanix, EVO: RAIL, Etc.);
  • OpenStack (Red Hat Enterprise Linux OpenStack platform).

Platform as a service (PaaS) is a category of cloud computing services that provides a platform allowing customers to develop, run, and manage applications without the complexity of building and maintaining the infrastructure typically associated with developing and launching an app.

Platform as a service (PaaS) is a cloud computing model that delivers applications over the Internet. In a PaaS model, a cloud provider delivers hardware and software tools — usually those needed for application development — to its users as a service. A PaaS provider hosts the hardware and software on its own infrastructure. As a result, PaaS frees users from having to install in-house hardware and software to develop or run a new application.

Platform as a Service offers advantages over managing your own development infrastructure and allows more time to focus on designing and coding. While PaaS may be the preferred choice for new projects, it may not be a good fit for existing, legacy development efforts.

Terasky’s vast experience in integrating complex development projects and our people, having a record of dozens development projects will figure out how to incorporate PaaS into your organization. We will advise which of the services allow you to move computation easily to the cloud while maintaining other functions on local resources, i.e. for copying your local Python code to the cloud and running it there, while your development tools and code repositories can stay local.

Another option is to develop with on-premises resources and test with a PaaS product. This approach is useful when you run a large test suite or need separate instances of shared resources to test properly. You can also move all your development to the cloud by using a cloud integrated development environment (IDE).

Applications often need to integrate with other apps or shared resources, like enterprise databases.

Terasky professionals will help you to understand how you will access those resources from PaaS. If you use an in-house application that implements a Web services API and already serves external client applications, you should be able to move to PaaS. If security is a concern and only client applications on a virtual private network (VPN) are allowed to access on-premises resources, test the API from a PaaS early in your evaluation. If you need to implement VPN functionality and your PaaS provider does not meet your needs, you may need to consider an Infrastructure as a Service (IaaS) cloud instead.

PaaS offerings support a range of languages, databases and other services.

Terasky team will assist you to find a PaaS option that supports your full application stack reduces the barriers to adopting PaaS for development. For example, if you are developing with Java and use Jenkins for continuous integration, then CloudBees may be a good option. If you need support for Ruby and Node.js,Engine Yard could work. If you’re building on the NoSQL platform, Red Hat’s PaaS, OpenShift, may be a good choice.

Where you are in your development process strongly influences the costs and benefits of shifting development from on-premises to the cloud. Typically, the farther along a project you are, the more investment you have in your development environment and tools. As the project progresses, you will need to create more software that must be moved to a PaaS platform, which increases the cost of making a switch.

Terasky team help you moving development of an ongoing project to a PaaS platform makes sense when the advantages of PaaS outweigh the costs and potential time required to make the migration. After moving to a PaaS Terasky professional services will relieved you of managing servers, operating systems and other infrastructure, build a process for to scale your application and avoid time-consuming and challenging engineering issues.

Running your application in a cloud that scales with minimal intervention on your part could save more time and money and is worth the effort of a move to PaaS.

Terasky partners with the leading PaaS vendors: RedHat OpenShift cloud development Platform, Google Cloud Platform, Google Application Engine, Google Big Data, Oracle Cloud Platform for Application Development, Oracle Cloud Platform for Data Management, Oracle Cloud Platform for Integration.

Terasky specialists will advise on PaaS Deployment choices and portability between public and private environment.

Software as a Service (SaaS) is a software distribution model in which a third-party provider hosts applications and makes them available to customers over the Internet. SaaS is one of three main categories of cloud computing, alongside infrastructure as a service (IaaS) and platform as a service (PaaS).

SaaS removes the need for organizations to install and run applications on their own computers or in their own data centres. This eliminates the expense of hardware acquisition, provisioning and maintenance, as well as software licensing, installation and support.

Terasky team can help in designing, architecting, integrating and supporting the chosen SaaS solution with the current Enterprise IT, including a comprehensive data protection, Disaster Recovery and Business Continuity solutions.

Terasky professional services team with different virtualization solutions (Vmware, Hyper-V. RHEV, Acropolis, Docker containers, Kubernetes) can help adopt the SaaS solution into enterprise virtualized environment, integrate it into Management system and automation solution.

Terasky can design and architect Hybrid Cloud solution containing SaaS cloud model with on premises private cloud.
