Popular cloud computing services: the IaaS (Infrastructure as a Service)

A popular type of Cloud service these days is Iaas. It is a means of keeping costs down in the flexible area of hardware needs.  Iaas or Infrastructure as a Service is designed around providing a user with the available hardware to host whatever project needs hosting.

The best way to think about this is you are paying for the use of a network like you would a tax on infrastructure.  One day you may have to use the subway, another day the roads, and then some days you have five trucks and a subway car on the infrastructure.  Infrastructure as a service gives you real or virtual hardware that you can upload your information to.  Your programs or the users of your webpage go through the infrastructure of the Cloud host.  The host gives you the availability of storage and memory that scales according to your needs, but you have to build the project from the ground up to make use of the available infrastructure.

Getting down to basics allows the customer or the company renting out the Cloud service to scale their operations according to their needs.  For some the question may be why go through the extra effort to provide your own platform.  The scale of your operation when you rent out virtual room in the Iaas system is more flexible this way.  While Paas offers more software services to the customer, the open nature of Iaas gives a more established flexibility to create their own services with the hardware rented out.  The provider has the hardware, whatever particular hardware services they are offering, and the customer rents it out to keep costs down.  Any large database needs to be kept in a cool dry environment, and this amongst other things drives costs up especially for a project with variable memory needs.

Many services are virtual server space, network connections, bandwidth, IP addresses and load balancers.  Like Saas and Paas, Iaas is accessed by a client through the internet.  The Cloud in general is essentially an Application or a Web page that accesses the server through the internet and creates available storage for the user. The provider is able to keep their own costs down by letting the customer base make decisions on what type of platform or software to install on their hardware.  In turn, everything works seamlessly together. The hardware of an Iaas provider is often stored in many different facilities, allowing them to provide a product of scale.  Basically they can rent out their hardware to other users and by having a large facility or facilities they are able to keep costs down that are passed on to the customer.

The customer does not have to rent out their own facility this way.  By not having to maintain their own facility they are able to scale their operation according to peak and low traffic times.  For instance a weight loss website might want to rent out from an Iaas or Paas provider to keep costs down during  lulls in business.  But after New Years they might acquire a lot of customers that providing for would be a huge expense the rest of year.

Between Iaas and Paas providers the user has to decide what type of operation needs they have.  For a developer Paas might be the way to go, but for a more established company, or a company that has a product in line for their users a Iaas provider will be able to give them the hardware they might need at a scalable rate meeting their needs as it is needed.  Time, money, efficiency and ease of use are important factors in any business and tuning into the correct providers is the way to go.

The Way Forward in Heterogeneous DataCenter Architectures

The use of heterogeneous datacenter architecture has been on the rise. Developers experience numerous challenges when trying to adapt applications and systems in such areas. The good thing with cloud computing is that it will abstract the hardware from the programmers and end users. This is a good idea for allowing the underlying architecture to be improved, such installation of new hardware, and no changes will be made to the applications.

The use of heterogeneity in processor architectures will help solve a number of problems. The elements for heterogeneous processing can improve the efficiency of our systems through features such as specialization, which are computations matching the elements which have been specialized for processing. The Graphical processing units (GPUs) are examples of systems which have developed in the computing industry. Others include media-functional units such as SSE4 instructional set, parallel coprocesors like Intel’s Xeon Phi and encryption units. The future architectures are expected to feature multiple processors, each with heterogeneous internal components, interconnects, accelerators, and storage units with good efficiencies. Companies which rely on large-scale datacenters like PayPal and Microsoft are investigating on how to implement heterogeneous processing elements so as to improve on the performance of their products.

Technology for developing cloud computing which can be integrated with the heterogeneity of the data center will make us look for ways for exploiting the varied processing elements for special purpose and we don’t need to lose the advantages associated with abstraction.

With infrastructure as a service, the physical and virtual resources will be exposed to the end user. Virtual machines will offer an instant control to the operating system (OS). In the traditional architectures, virtualization introduced a great overhead for workloads are highly sensitive to the performance of the system. However, modern technologies such as peripheral component interconnect (PCI) and single-root I/O virtualization (SR-IOV) have reduced this overhead since they perform a direct access to the accelerators and the networking devices, and the incurred overhead is far less, maybe 1%.

Also, with the increase in heterogeneity of the datacenters, the deployments for IaaS should be expected to expose varied components. For us to extend to the heterogeneous IaaS deployment from the homogeneous cloud flexibility, we have to perform a further research on the following fileds:

– The schemes which can be employed for sharing in accelerators.
– Optimal tradeoffs associated with virtualization functionality and performance.
– Optimization techniques for power and utilization.
– Scheduling techniques for determination of job assignments for the resources to be allocated more efficiently.
– Schemes for cost and prioritization.
– Mechanisms for migration of jobs with state in the accelerators and the host in accelerators.

Heterogeneous computing should involve finding ways to exploit the available new interconnect technologies such as the parallel file systems, software-defined networking in relation to the heterogeneous compute elements.

For the case of platform as a service, the heterogeneity has to be exposed to the framework, or exposed to programmer, or hidden by backends targeting heterogeneity, or hidden by the libraries. Future research should be focused on the following:

– Software architecture regarding accelerated libraries.
– Scheduling mechanisms aware of heterogeneity at the level of the platform.
– Application programming frameworks with the capability of exposing or not exposing the heterogeneity to the programmer.
– Allocating resources amongst multiple frameworks or platforms in an heterogeneous manner, or for the frameworks which share the same datacenter.

The catapult framework for Microsoft is an example of a research which is targeting to improve on the heterogeneous hardware. The software was created for the purpose of improving how the performance of Binge Search Engine. It will provide us with a valuable use case on how to exploit the heterogeneous hardware for applications in commercial datacenters.
