ETL Process Explained

 ETL is the abbreviation for “extract, transform, load” and it enables organizations to collect and copy data from various sources into a single, centralized system. Different types of data are collected and refined by an ETL process. This data is then delivered to a data warehouse. Moreover, it enables the migration of data among multiple sources, destinations and analytical tools. An ETL process not only aids in executing strategies for data management but also provides business intelligence.

 An adequately designed ETL system is important for strategies that involve data integration and is usually used in data warehousing. An ETL process ensures the extraction of data from source systems along with enforcing standards for consistency as well as data quality. This process makes it possible for separate data sources to be used together and for various types of data to function together seamlessly and consecutively delivers data in a presentable form enabling application developers to build applications and end users to make decisions.

The process of data extraction extracts data from sources that are either homogenous or heterogeneous. Data is processed in the data transformation step with the aid of data cleaning. Additionally, the data is moulded into a structure or storage format that enables querying as well as analysis. Last but not the least is the step of data loading which involves the insertion of data into the corresponding database (a data warehouse, an operational data store, data mart etc.). ELT systems involve data integration from various applications which are developed and supported by different vendors.

To digress, the websites that we access also have data. This data is stored on the servers of web hosting companies and delivered from there via the Internet, upon user request, to ensure that websites are accessible. Web hosting services can be of various types and the most efficient web hosting services are usually referred to as the “Top Cloud Hosting”, the “Best Linux Shared Hosting”, the “Best Windows Shared Hosting” etc.

The ETL Cycle

A real-life ETL cycle will have certain steps with regard to the process’ execution, such as cycle initiation, building reference data, extracting from sources, validating, transforming, loading into staging tables, auditing reports, publishing and finally archiving.

The Functioning of ETL

There are three steps that are essential to the ETL process. These steps enable the integration of data from source to destination. These three steps of an ETL process are data extraction, data transformation and finally data loading. Let us touch upon these steps individually.

1. Data Extraction

Usually businesses rely on multiple data types as well as systems. Such complex data needs to be extracted from its source prior to being moved into a new system. The first step of the ETL process has to do with data extraction and entails not only importing but also consolidating structured and unstructured data into a single repository. Sources for data extraction include Cloud, hybrid and on-premises environments, data storage platforms, data warehouses, existing databases, legacy systems, CRM (Customer Relationship Management) systems, mobile devices and applications, marketing and sales applications and analytical tools. By automating the process involved in data extraction, ETL tools ensure an efficient and reliable workflow and save time as well as eliminate manual errors.

2. Data Transformation

The second step in an ETL process has to do with data transformation. This phase entails the application of rules and regulations for ensuring accessibility to data and its quality. Additionally, such rules can be applied that aid an enterprise in meeting reporting requirements. The phase of data transformation has many steps. These are mentioned below-

• Cleansing- In this step data-related inconsistencies and missing values are resolved.
• Standardization- This step applies formatting rules to a data set.
• Deduplication- In this step redundant data is discarded.
• Verification- This step ensures the removal of unusable data.
• Sorting- Data organization based on its type takes place in this step.
• Other tasks- The quality of data is enhanced by applying optional or additional rules.

The data transformation phase is usually considered as the most crucial phase of the entire ETL process as it ensures enhancement in data integrity and delivers data to its next destination in a form that is compatible and can be used readily.

3. Data Loading

As the last step in the ETL process, data loading loads the transformed data. This loading of data can take place at one go, which is known as full loading or it can happen at scheduled intervals, which is called incremental loading.

Conclusion:

Enterprises these days rely on efficient ETL tools to facilitate their data integration processes. Such tools provide not only speed, cost-effectiveness, reliability but are also aligned with a business’ data management strategies and deliver augmented productivity and efficiency.

What is a Community Cloud?

 Cloud computing’s benefits have ensured that it is rapidly becoming an important part of most businesses’ functioning. It is of four types: private, public, hybrid and community cloud. The focus of this blog is on the concept of community cloud.

A Community Cloud

A community cloud is essentially a private cloud’s hybrid form. Community clouds are multi-tenant platforms and make it possible for various companies to function on a shared platform. This ensures that many clients can work on joint projects as well as applications, which require a centralized cloud infrastructure. A community cloud refers to an infrastructure that is distributed and which is meant to solve certain specific issues of businesses. This is attained through the integration of services that are delivered by various types of cloud solutions. Community clouds aid their users in identifying as well as analysing their business demands. A data center can host a community cloud or it can be owned by one of the tenants or by a third- party provider of cloud services.  It can be either on-site or off-site and is owned, managed as well as operated by one or more businesses or by a third party or by both together.

A community cloud deployment model is shared among multiple businesses/tenants that operate within a certain domain, which is common to all of these entities. Hence, access to a community cloud is restricted to these entities. In a community cloud a group of businesses share a multi-tenant setup. This is used by businesses for joint ventures as this cloud infrastructure enables access to systems and services by a group of several businesses for the purpose of sharing information. In it the costs are spread over a lesser number of users as compared to that in a public cloud. Hence, it doesn’t deliver fully the cost saving potential of cloud computing.

A community cloud isn’t different technically from a private or a public cloud. This multi-tenant data center enhances companies’ efficiency and performance. It also maintains standard protocols with regard to security, privacy, implementation, management and usage of the centralized cloud. An example of the usage of a community cloud is for testing high-end security products. It can also be used to test certain features of a public cloud environment.

In a nutshell, a community cloud refers to a form of collaborative effort which involves sharing of infrastructure among many businesses that belong to a certain community and have common concerns, such as security, compliance etc.

To digress, cloud technology is used in cloud hosting, which is a type of web hosting service that is provided by a web hosting company for making websites accessible over the Internet. The best web hosting service providers are known as the “Top Cloud Hosting Company”, the “Best Website Hosting Company”, the “Best Windows Hosting Company” etc.

Major Sectors that Utilize Community Clouds

The main sectors that utilize community clouds are the healthcare industry, media industry, public sector, scientific research, energy and other core industries etc.

In the healthcare industry, community clouds deliver a global platform on which information as well as knowledge can be shared without the risk of sensitive data that is maintained in the private infrastructure getting revealed. Companies that are in the media industry require simple and low-cost solutions for enhancing media contents’ production’s efficiency. Community clouds deliver a shared environment for business collaborations in the media industry and boost aggregate bandwidth, CPU as well as storage that is required for carrying out media-related work efficiently. Public sector’s legal and political restrictions limit the usage of public clouds. A distributed environment is provided by a community cloud for creating a communication platform for the performance of the operations in the public sector. Scientific computing is the shared interest for the adoption of community clouds in scientific research. In the sector that has to do with energy and other core industries, community clouds bundle solutions that collectively address the management, orchestration as well as deployment of operations and services.

Community Cloud’s Advantages

There are many advantages of a community cloud. These are as follows-

• It offers better cost-effectiveness than other cloud models
• It provides scalability along with flexibility
• A community’s requirements are met by the protocols and the configuration in community systems
• Ensures enhanced availability and reliability with regard to a community
• Community clouds ensure openness as these are open systems
• Community clouds do away with the dependency on cloud service providers

Community Cloud’s Disadvantages

The main disadvantages of a community cloud are mentioned below, in no particular order.

• It has lower bandwidth capacity along with limited storage
• It is challenging to maintain its security standards without skilled IT staff
• Setup costs are increased by it
• There are always consistent maintenance costs
• It doesn’t deliver the full benefits of either a public cloud or a private cloud

Conclusion:

Requirements that are specific to certain industries are addressed by community clouds while ensuring the cost-effectiveness that is provided by a public cloud. Community cloud computing provides a cost-effective solution with lesser complexities with regard to the cloud environment and ensures applications’ security.

Reduce Loading Time of Website

Being patient is good to follow. But this term does not work on internet. Internet is designed to complete your work in very small span of time. Internet users are really in hurry. They want to complete each and everything in single click. Internet user will stay on those websites that has high response time and taking less time to load. According to Yahoo experts, 80% of web page’s load time is spent in downloading different parts of webpage like – images, stylesheets and scripts. Follow below points to reduce loading time of website.

• Reduce HTTP request – HTTP request is made for each elements. On-page components takes more time to load. And web page will take longer time to render. Minimize your HTTP request to figure out how many websites that are taking time to load. Use Google developer tools to find how many HTTP requests your website makes. In google chrome developer tools, click on “Network” tab. Then click on “Name” column shows all of the files on web page. The “Size” columns shows size of each file. And the “Time” column shows how long it will take to load each file. To see number of request click on the bottom left corner. Reducing the number of request will speed up your website. Look carefully in your files and see if there are any unnecessary requests.

• Don’t use large images – Avoid using large images, large images can cause to load web page. You can set width and height attributes of <img> elements in HTML. Use image editor, you will find many image editors to resize the image as per required dimensions. The lower the image size, thus helps to decrease load times.

• Cache web pages – CMS (content management system) dynamically generates web pages. Always statically cache your web pages and database queries to decrease strain on server. This also helps in speed up page rendering times. Caching web page saves a static version and saves user to recreate web page every time it is requested. CMS like – WordPress checks out WP super cache and W3 total cache.

• Reduce 301 redirects – 301 forces web browser to new URL. This increases web page loading times.

• Choose hosting provider – New website owner’s tries to find out cheapest hosting provider. While you may found affordable in the beginning. But choosing cheap hosting services without even thinking for the second time could cost you in future. Don’t choose any random hosting provider. Research the market and choose hosting provider that you can trust. There are many hosting providers such as HTS Hosting, best hosting company in India provides Linux dedicated hosting, Windows dedicated hosting and other hosting plans. Choose web hosting plan according to your business.

• Reduce server response time – DNS lookup also plays important role in web page loading. ISP (internet service provider) performs DNS (domain name system) lookups to find IP address associated with URL. DNS lookup finds specific DNS record and directs requested web page.

• Enable Compression – Smaller files helps to load web page faster. Compressing files is one of the easiest way to reduce load time. There are many tools that are used in compressing large files. Such as – Gzip. Most web server compresses files using Gzip.

Conclusion: -

Thus, reducing loading time on website give high amount of traffic and good revenue to the business.

Multi-Cloud Management’s Challenges

 Nowadays more and more businesses are using cloud technology due to its numerous benefits, such as reduced IT costs, scalability, flexibility with regard to work practices etc. With an increase in the deployment of applications through public as well as private clouds, there is a rise in the demand for cloud management solutions. Multi-cloud management aids in creating a uniform as well as consistent system for managing applications and workflow in the cloud. It serves to organize large volumes of data in order to ensure that a single cloud platform doesn’t get overloaded. Multi-cloud management optimizes various cloud vendors’ services. Moreover, it ensures data security, deployed apps’ performance updates continuously along with unified visibility with regard to all cloud services.

Cloud analysis, self-service capabilities and workflow automation can be easily attained through a multi-cloud management system. Cloud monitoring and analysis enables one to avail the best services that suit one’s requirements. Self-service capabilities do away with the traditional processes associated with IT resource provisioning. Workflow automation eliminates the need for human intervention in building and managing computing instances.

Selecting the most Appropriate Multi-Cloud Management Platform

Certain features need to be taken into account while selecting an appropriate multi-cloud management platform. These include provisioning, monitoring and orchestration of service, service performance, service governance and monitoring analytics. Let us touch upon each of these features. In the context of service provisioning, the chosen multi-cloud management platform should be able to launch as well as allocate cloud services on demand. Moreover, the tool should translate the console’s provisioning request or an API (Application Programming Interface) and consecutively translate it into the cloud-native API of the target cloud that is within the multi-cloud platform in order to ensure the application’s best performance.

A multi-cloud management platform should be capable of evaluating and visualizing applications as well as network-layer performances between private cloud, public cloud and hybrid cloud services. This should include reporting of occurrences which helps to determine the particular service’s use in the future, its reliability and cost metrics etc. Additionally, it should be able to monitor service performance and subsequently log the resulting data.

Service governance specifies and leverages policies that have to do with the usage and execution of a service/ services. This feature helps to audit the various services of one’s multi-cloud environment. The feature of service orchestration ensures the orchestration of a cloud service to meet the needs of a business process. Moreover, there should be a feature to monitor analytics in order to get a detailed analysis of a cloud’s behaviour.

Before proceeding and discussing the challenges that are involved in the management of a multi-cloud platform, let us digress and touch upon cloud hosting. Cloud hosting uses cloud technology and is a type of web hosting service that is provided by a web hosting company. It is meant to make websites accessible over the Internet and uses cloud servers to store the files of websites and delivers those files to make websites accessible. The best hosting service providers are usually referred to as the “Best Website Hosting Company”, the “Best Windows Hosting Company”, the “Top Cloud Hosting Company” etc.

Challenges Involved in Multi-Cloud Management

The major challenges that are involved in the management of a multi-cloud platform are mentioned below.

• Performance- Running checks periodically on one’s web/ mobile apps with regard to speed and performance becomes challenging in the complex environment of a multi-cloud.

• Compliance- The division of the processes that have to do with planning and approval, into numerous sections within a multi-cloud environment, causes an increase in compliance issues. This can result in shadow IT, security problems etc.

• Data security- Robust security measures need to be in place for multi-cloud environments. The constant data exchange between multiple clouds can increase the risk of threat to data security.

• Costs- Inefficient multi-cloud management can cause one to incur unnecessary expenses. If one has integrated multiple cloud services in one’s application and for some reason is not able to utilize all the services to their full capacity, one will still have to pay for those services that have not been accessed.

• Cloud sprawl- A cloud sprawl is caused by the failure of users to decommission those cloud computing services or instances that have not been utilized. This leads to challenges in resource visibility. Moreover, it affects the overall expenses with regard to the cloud.

• Delays- When such workloads need to be managed which are running on multiple and varied platforms, then there is a requirement to address real-time orchestration and processing. Often there are delays in delivering results on time, due to this.

• Migration- Migrating to a multi-cloud environment can be challenging for most enterprises. Efficient multi-cloud management becomes a priority for organizations when it comes to migrating their work while maintaining their standards and policies in the new multi-cloud set up.

The Best Practices for Managing a Multi-cloud

It is essential to consider the best practices for managing multi-cloud environments. These have to do with mapping one’s architecture based on one’s requirements, integration, consumption, usage of containers, maintaining a secure environment and ensuring that disaster recovery measures are in place.

One should map one’s entire network in order to identify and understand the cloud’s role in one’s overall strategy for system-management. In the context of consumption, each business unit of an enterprise in a multi-cloud environment, uses the services of multiple providers. Moreover, usually these units pay for these services in different ways. Hence, it becomes essential to evaluate each unit’s usage (consumption) first and then allocate the resources accordingly.

It is recommended to use containers in multi-cloud environments. Portability can be improved by packaging applications along with their dependencies. Additionally, it aids in simplifying management and renders it easy to migrate applications to different cloud environments without causing any disturbance in their performance.

It is extremely important to take into account the seamless integration of the various components of a multi-cloud environment. Common standards are needed by developers for the purpose of integrating as well as managing the supplier ecosystem in a multi-cloud, in order to address any problem effectively. This integration has to be in governance, organization, business, processes, tools and information. Another important practice requires maintaining a secure environment, as security related issues have been one of the main challenges for businesses when it comes to adopting a multi-cloud platform. Ensuring secure transmission of sensitive information among the various clouds should be every enterprise’s prime responsibility. Hence, it is important to monitor access to data and ensure that role-based access control is provided to those employees of a company who access the multi-cloud. Continuous as well as adaptive security measures need to be maintained and followed. Last but not the least, it is essential to have a disaster recovery plan in place. Such a plan ensures that there isn’t any data loss if an untoward incident takes place.

Multi-cloud management might be challenging but those challenges can be mitigated to a large extent by following the best practices for managing a multi-cloud platform.

Optimize VPS for website

 VPS (virtual private server) uses virtualization technology that provide dedicated resources to end-users. Different VPS can be installed in single dedicated server. VPS generally resides in parent server. Dedicated VPS hosting environment is created on dedicated server or the cluster of servers. VPS replicates many of properties of dedicated server. VPS acts like dedicated server but in reality it acts like a software emulating dedicated hardware. There are many hosting providers such as - HTS Hosting, best hosting company in India provides Windows shared hosting, Linux dedicated hosting, VPS hosting and other hosting plans.

Benefits of VPS (virtual private server): -

• Increase Performance – VPS increases performance unlike shared hosting plans where hundreds of users shares same server. Sometimes websites that are running on shared hosting can cause functionality problems. For example- websites that are receiving high amount of web traffic can slow down other websites on the server. By using VPS, functioning of your website will never regulated by other websites.

• Great Control – Great control offers root access. Without root access you have to only rely on software packages that are provided by hosting provider. If website owners is looking to use specific software that is not supported and provided by hosting provider. This could cause issues and may prevent website owners to work independently. But with VPS, you will get root access and you can implement necessary software changes within the server.

• Low Cost – Many companies prefer to use VPS rather than choosing dedicated server. Dedicated server has higher cost comparing VPS. Many hosting providers has price of VPS more than price of shared hosting.

• Scalability – If you are looking to grow your business and you expect high amount of web traffic. And you require server to accommodate this. For good scalability VPS is much lower in cost and gives resources same as dedicated server. Unlike Dedicated server which is higher in cost.

VPS Optimization: -

Start looking closely at apache configuration. Poor configuration can leads to unnecessary use of server’s resources and poor configuration can impact other processes. You can optimize performance of VPS for website. You can improve VPS by adjusting MaxClients, KeepAlive, StartServers and MaxRequestChild.

• MaxClients – Directive limits the no. of concurrent requests that are served. Any request attempts above this limit will be queued. Recommend limit for MaxClients is 150.

• KeepAlive – KeepAlive should always be “on” unless server is receiving concurrent requests from large number of IPs constantly. Load balancer and high volume should always turned off to boost connection throughput. KeepAlivetimeout should set its value from lowered to 5.

• StartServers – Here directive sets the no. of child server processes created on start-up. StartServers value should be set to 5.

• MaxRequestsPerChild – Directive limits the no. of requests that every single child server processor handles. Whenever no. of requests reaches to specified values. Child process will die. Recommended value limit is 300.

• Cache your web content – Web caching is another way that helps in improvement of VPS. Continuously requesting static files makes slow and heavy process. But caching RAM can improve your speed and reduce latency through temperature storage. Caching software includes Varnish, a powerful cache that helps in improvement of dynamic websites. And Memcached helps in caching system that are heavily relies on databases.

• Optimize Your Website Content – There are different ways to optimize content to deliver more effectively. You can find different tools on the internet. That analyses website and finds issues and offers suggestions to improve your website. For example – Google’s PageSpeed and WebPageTest.org. Both of the tools will provide accurate speed and detailed performance measures. These tools show results in the range of performance and provides detailed feedback on improvement of back-end and front-end configuration.

Conclusion: -

Optimizing VPS can really help to create revenue and profit through your website. Though VPS has many benefits and can be used in various activities.
