Beginners Guide To Cloud Computing

Cloud computing is a method of delivering computing services including servers, storage, database, networking, software, and analytics over the internet. This helps in ensuring faster innovation, flexible resources, and easy scalability. The main purpose of cloud computing is to grant user access to data centers. Using cloud computing, users can access data from remote servers.

Types Of Cloud:

  1. Private Cloud: It is used for intra-business interactions, where the computing resources are deployed for a single organization.
  2. Community Cloud: In this type, the computing resources are deployed for a single community and organizations in the community.
  3. Public Cloud: This type of cloud computing is used for B2C interactions and the computing resources are owned by government or an academic/business organization.
  4. Hybrid Cloud: It is used for both B2B and B2C interactions. The computing resources are bound together by different clouds.

Cloud Computing Services:

  1. Software as a Service (SaaS): It is a software distribution model in which the cloud services are hosted by a service provider and made available to the client over internet. Clients can subscribe to the software and pay for monthly usage.
  2. Platform as a Service (PaaS): It provides a platform to developers for building applications and services. PaaS services are regularly updated with new features. It includes software support and services, storage, networking, deploying, testing, collaborating, hosting and maintaining applications.
  3. Infrastructure as a Service (IaaS): It provides computing infrastructure like virtual server space, network connections, bandwidth, load balances, and IP addresses. The pool of hardware resources is extracted from multiple servers and networks distributed across numerous data centers.

Benefits Of Cloud Computing:

  1. Cost Effective: Cloud computing eliminates the capital investment required to buy hardware/software and set up on-site data centers. It also reduces the cost incurred on hiring IT professionals for running and maintaining the data centers.
  2. Speed: Cloud computing allows businesses to be flexible and ensure seamless capacity planning. Also, cloud computing services are delivered on-demand, so vast amount of computing resources can be provisioned in a short time.
  3. Productivity: On-site data centers require a lot of hardware setup, software patching, and other IT management tasks. Cloud computing removes the need for these tasks, thus freeing the time and resources of IT team which can be focused on other productive tasks.
  4. Lesser Downtime: Cloud services allow businesses to bring data centers closer to the users, irrespective of their geographical location. This helps in reducing the downtime.

Trending Technologies In IT Industry

As technology is evolving rapidly, it has enabled a faster change and greater progress in the IT industry. The disruptive technological trends like interconnected humans, robots, devices, content and services driven by them have become an integral part of modern IT applications.

Some of the major technology disruptors revolutionizing the IT industry are:

  • Robotic Process Automation (RPA): It is an emerging form of automation technology that uses software with artificial intelligence and machine learning capabilities. RPA is used to perform high-volume repetitive tasks that awere earlier done by humans. The RPA robots utilize the user interface to capture data and manipulate applications like humans do.
  • Internet of Things (IoT): IoT enables devices, home appliances, cars, etc. to be virtually connected and exchange data over the internet. The connected devices share data that they collect and take instructions from multiple sources which may or may not be in close proximity. Proper use of IoT technology can enable optimized traffic system, efficient waste management, energy use, etc.
  • Cloud Computing: The major part of the IT industry relies on cloud computing, making it one of the most trending technologies. The range of cloud solutions & delivery models is widening and it now requires the cloud services to be more adaptable in different areas of activity. Majority of IT service providers are acquiring hybrid cloud solutions to speed up the service delivery.
  • Blockchain: Blockchain technology has potential applications in almost every field. We have already witnessed use of blockchain applications in healthcare, IT, real estate, law enforcement, cryptocurrency, banking, etc.
  • Artificial Intelligence (AI): AI are computer programs that perform highly intelligent tasks, such as recognition of images, speech, patterns and complex decision making. Machine learning is a new branch of AI that is creating and enabling smart business operations with greater accuracy.
  • Data Security: Cybersecurity is increasingly evolving due to technological advancements. As the threats are constantly arising and the hackers are finding better ways to illegally access information, technologies are required to enhance data security by incorporating hardware authentication, cloud technology and deep learning. This makes data security an emerging technology as it will constantly evolve to defend against intruders.

Implementation of modern technology in business operations, marketing, customer care, etc. can increase productivity of an organization. For more information about various trending technologies and how they can be applied within your organization, call Centex Technologies at (972) 375 - 9654.

Pros & Cons Of Serverless Computing

Although the term ‘Serverless Computing’ implicates the existence of a computing architect with no server, it actually defines a cloud based execution model. The server is hosted by cloud service providers and users are not required to buy it or set it up onsite. The cloud service provider manages the server and machine resources are allocated to users.

As most businesses are making a shift towards serverless computing instead of traditional approach, it is necessary to understand the pros & cons of this approach.

Pros Of Serverless Computing:

  1. Cost-effective: Serverless computing is a cost-effective approach for businesses. The users are required to pay as per the amount of resources consumed by their application instead of pre-purchased units of usage capacity.
  1. Easy To Scale Up: In case of serverless computing, application developers are not required to implement a code for scaling up. Also, it rules out the need and cost for upgrading existing servers or adding new server units. When considering to scale up, businesses can request additional resources from the service provider and pay according to their consumption. Also, cloud systems are more elastic as they are capable of scaling up and down inherently according to the demand.
  1. Low Human Resources Cost: Serverless computing eliminates the need for onsite servers. Thus, businesses are not required to hire staff for managing and operating the hardware. This helps them save cost that was traditionally incurred on human resources.
  1. Enhanced User Experience: By switching to serverless computing, the businesses and application developers can save time and resources required for server management. These resources can be used on other tasks such as improving productivity and user experience by developing as well as improving customer-friendly features.
  1. Decreased Latency: Depending upon the services offered by the provider, businesses can choose to run the application functions on a server node close to the end user. Thus, it reduces latency as the requests initiated by a user are not required to travel to origin server and can be reverted from the nearest available node.

Cons Of Serverless Computing:

  1. Testing Becomes Challenging: A serverless environment cannot be easily replicated to check how an application code will respond after being deployed. Also, developers do not have visibility into backend processes and the application is split into separate functions for running on the cloud. This makes it challenging to debug any arising issues.
  1. Vendor Lock-In: When using a cloud based server, the developers are restricted to adapt the rules set by the third party vendor such as using a specific coding language.
  1. Multitenancy: In order to avail maximum benefit, cloud service provider may run applications or software for numerous different users on a single server. Although workloads of different customers are isolated, there may still be bugs in initial offerings. This gives rise to data security risks.
