ARE YOU IN THE CLOUD?

Cloud computing is internet based computing that provides shared computer processing resources and data to computers and other devices on demand. It enables ubiquitous, on-demand access to a shared pool of configurable computing resources. Cloud computing and storage solutions provide users storage and processing of their data in third party data centers. It allows companies to avoid up front infrastructure costs like purchasing servers, focus on their core businesses, get applications up and running faster with improved manageability and less maintenance and enables information technology (IT) teams to more rapidly adjust resources to fluctuating and unpredictable business demand. So how does it work and how can you benefit from it?

 

A public cloud is services rendered over a network that is open for public use. A private cloud is cloud infrastructure operated solely for a single organization, whether managed internally or by a third-party and hosted either internally or externally. A community cloud shares infrastructure between several organizations from a specific community with common concerns whether managed internally or by a third-party and hosted internally or externally. A hybrid cloud is a composition of 2 or more clouds that remain distinct entities but are bound together, offering the benefits of multiple deployment models. A distributed cloud is assembled from a distributed set of machines in different locations, connected to a single network or hub service. A distributed cloud is either public-resource computing or volunteer cloud computing. The intercloud is an interconnected global “cloud of clouds” and extension of the internet “network of networks”.  Multicloud is the use of multiple cloud computing services in a single heterogeneous architecture.

 

Cloud-computing services offer 3 standard models. Software as a Service (SaaS), Platform as a service (PaaS) and Infrastructure as a Service (IaaS). SaaS is where users can access provider’s applications on a cloud infrastructure. The applications are accessible from various client devices through a web browser or program interface. The user does not manage or control the cloud infrastructure except for user-specific application configuration settings. PaaS is where users can deploy onto the provider’s cloud infrastructure consumer-created or acquired applications. The user does not manage or control the cloud infrastructure but has control over the deployed applications and user-specific application configuration settings. IaaS is where the user has access to processing, storage, networks and other computing resources and can deploy and run software. The user does not manage or control the underlying cloud infrastructure but has control over operating systems, storage and deployed applications and control of select networking components. Also, Mobile “backend” as a service (MBaaS) is offered to web app and mobile app developers to link their applications to cloud storage and cloud computing services with application programing interfaces (APIs) exposed to their applications and custom software development kits (SDKs). Services include user management, push notifications and integration with social networking sites.

 

Cloud providers typically use a “pay as you go” model. Cost reductions are claimed by cloud providers. It converts capital expenditures to operational expenditures. This lowers barriers to entry with infrastructure provided by a third party. Less in-house IT skills are required for implementation of projects.

 

Device and location independence enable users to access systems using a web browser regardless of location or what device they use. As infrastructure is off-site and accessed via the internet, users can connect from anywhere.

 

Maintenance of cloud computing applications is easier because they don’t need to be installed on each user’s computer and can be accessed from different places.

 

Multitenancy enables sharing of resources and costs across a large pool of users allowing for centralization of infrastructure in locations with lower costs, peak-load capacity increases and utilization and efficiency improvements.

 

Performance is monitored by IT experts from the service provider and consistent and loosely coupled architectures are constructed using web services as the system interface.

Productivity can be increased when multiple users can work on the same data simultaneously. Time is saved as information doesn’t need to be re-entered when fields are matched. Users don’t need to install application software upgrades to their computers.

 

Reliability improves with the use of multiple redundant sites.

 

There is scalability and elasticity via dynamic provisioning of resources on a fine-grained, self-service basis in real-time without users having to engineer for peak loads. Users can scale up when usage needs increase and scale down when usage decreases.

 

Security is improved with centralized data and increased security-focused resources. There are concerns over loss of control of sensitive data and lack of security for stored kernels. Security is usually better than traditional systems because service providers have more resources and technical skills than users for security issues. The complexity of security is increased with data distributed over a wider area and greater number of devices in multi-tenant systems shared by unrelated users. Private cloud installations are used by users to retain control over the infrastructure and information security.

 

So now you know the opportunities of cloud computing and how you can benefit from it. Are you in the cloud? Why not? Cloud computing can reduce overhead costs, improve productivity and increase profitability. Let me know how I can help. Here’s to your success.
