Considering MongoDB as an Option for Database

index

For all the application database is the most important factor that requires more attention. While saying database the first thing that comes to our mind are RDBMS, relational algebra, ER-diagrams,etc.. But the most problematic thing is JOINS associated with all these. If you want to experience a  clear RDBMS functionality, at the same time you want to  rid of all the JOINS ,then MongoDB is the best option.

The entire world is moving towards Nosql , MongoDB has been one of the biggest contributors in this direction.

Lets have a look at the reason behind Nosql in terms of MongoDB,

Storage

In MongoDB,storage of all the business data is like those in the real world. You can easily establish a link between your business objects and the database collections and tables.

Lack of JOINS

Most of the database insert/update/Query time is wasted in joins. In present day applications performance is the key factor and joins are the real killers. Mongo has no joins. All the related objects are stored in related format which is almost like a predefined join.

No frequent change of RDBMS table structure

Earlier you might have changed your table structure frequently and ended up fixing issues because of that. It is really a time consuming task. Whereas , MongoDB is schema free. That actually refers, each document(ie.row) in a collection (table) can have different structures. So in conditions where things are extremely agile like startup/college project/proof of concept project, MongoDB is the preferred one.

No paid service

MongoDB is available  as an open source environment. So you need not worry about the cost and complexities of deploying it. There are many cloud providers like AmazonEC2,RedHat, VMware, etc..

Good driver support

MongoDB offers best driver support. Native drivers like Java, ruby, c++, python, etc..are already available.

Visible performance

MongoDB has proven track record. It is used in companies like FourSquare, SourceForge, GitHub, etc..

Community support

How to build a secure and scalable ECommerce platform?

online shoping

  • Nowadays it evident that many of the ECommerce portals are getting large number of concurrent users. So the software solution providers started to build a secure and scalable ecommerce applications which will handle huge number of concurrent users that are simultaneously accessing the platform.
  • Most of the enterprises recognizes that they need to get into online now more than ever! Grocery chains, Fashion apparels, tire manufactures, jewelry stores almost everyone in the business realizes that they need to quickly adopt digital market place. A shift from the conventional desktop to mobile applications shows where the focus is moving to. So, it is mandated to stay relevant for what the future holds.
  • As a technology driven company with focus on helping the clients in digital marketing, Veltrod is equipped to enable the business transformation for enterprises.
  • As many people things, Ecommerce stores does not provide “one size fits all” solution. Each and every business has a different consumer products, demographics and marketing channels. Whatever the case, the sales cycle could be random, consistent or seasonality peaks. So the solution is to tailoring the solutions which is flexible and an exact fit to the business needs. We at Veltrod identify the correct configuration of components that is required to make up your ECommerce store which will help to optimize the costs and create better visibility over your marketing expenses.
  • As the ECommerce industry is undergoing a major boom across the world and creates an opportunity to buy any product he is looking for, our clients require us to develop an online stores which can cater to huge traffic with few hundred thousand visitors accessing and making transactions on the platform at the same time. Being an industry leader and having an experience in developing similar Ecommerce portals, we build an online store which will allow users to buy a product and make a payment online in a secure manner.
  • Wherever we expect huge number of concurrent users to access the ecommerce platform, Veltrod host the ecommerce portal on Amazon Web Services (AWS) cloud. We consider the expected traffic over the next few years along with the expected transactions after the launch of the platform in consultation with the client. Our Architect will design the platform with AWS’s dynamic auto scaling facility which enables it to scale up to any amount of concurrent users and transactions. We use Elastic Load Balancer (EBS) and also multiple availability zone to ensure high availability and have consistent performance. We use Virtual Private Cloud (VPC) to make the platform secure. We go with AWS S3 for highly reliable and extremely scalable cloud storage to take care of the backups and provide additional layer for data security.
  • We have successfully hosted and managed several eCommerce stores on the Cloud.

How do I stay safe from the dangers of cloud computing?

Cloud computing is the big buzz these days and we have more choices available to us now than ever before. How many of us use Dropbox, SkyDrive, or Google Drive on a daily basis? How many big businesses rely on Amazon’s CloudFront for content delivery? Even Google Docs is a marvel with its cloud-based office suite. But despite the usefulness of cloud computing, it does have its drawbacks.

  • To choose the right Cloud

    c

  • There are a lot of cloud services out there and the number of choices will only continue to grow in the coming years. This means that you owe it to yourself to carefully research and consider all available alternatives before committing to any particular service. For example, if you need a cloud storage solution, it’s in your best interest to thoroughly check out Dropbox, Google Drive, SkyDrive, Amazon Cloud Drive, etc.
  • Due to the nature of cloud computing, data migration between clouds can be a huge timesink and pain in the neck. First you have to download all of it off the first cloud and then upload it all to the second. Even if there’s an import option, you’ll lose a ton of time depending on how much data needs to move. Do hard research and make sure you start off on the cloud that best fits your needs.
  • Keeping Multiple copies 

cc

  • One of the biggest risks of using a cloud is that the cloud’s longevity is entirely outside of your control. It could be there one morning and gone the next. Therefore, you should NEVER use a cloud as your sole location for data storage.
  • Yes, cloud storage is hailed as a revolutionary breakthrough when it comes to backups. I don’t disagree here as long as the cloud’s copy of your data is actually a backup (i.e., not the original copy) because if the cloud goes down, your data goes down with it in the blink of an eye. Use other backup solutions in tandem with cloud storage.
  • Another reason to keep local copies of data: temporary cloud outages. What happens when you find three hours to work on that project of yours, sit down, log into your cloud… and it’s down? Suddenly you’re impatiently waiting for the cloud to come back up so you can make use of your time well. With local copies, you’re never at the mercy of your cloud’s uptime.
  • Securing your data

ccc

 

  • Cloud computing has many upsides, the chief advantage being that all of the data management is done by the cloud provider. It relieves you, the user, from having to worry about overhead and administration. However, this comes with the potential sacrifice of security and privacy.
  • Since all of your data is being held by someone else, cloud services are inherently risky. We already discussed the possibility of losing all of your data when a cloud provider goes belly up overnight, but there’s also the issue of data confidentiality. What happens if the cloud provider is hacked? What if their data – which is actually your data – gets leaked by a rogue employee? What if they give up your data in light of a government subpoena?
  • It comes down to this: don’t put data on a cloud if you wouldn’t be comfortable with that data being exposed at some time in the future. You just can’t know beforehand that your data will remain secret forever.

Innovations in cloud computing

Cloud

  • In only a couple short years, distributed computing has taken the corporate world by tempest. As indicated by a late study led by IBM and the Economist Intelligence Unit, 67 percent of organizations with incomes not exactly U.S. $1 billion have embraced cloud at some level. Organizations perceive that having the capacity to share assets changes the financial matters of business by disposing of the weighty spending plans that accompanies devoted equipment. It’s a win-win circumstance. The organization spares cash while its representatives invest less energy in IT support. Everyone is glad.
  • Be that as it may, those that convey cloud in their business to exclusively spare cash are simply beginning to expose what’s underneath of what cloud can. Indeed, organizations that are barely centered around utilizing cloud to cut expenses will find that before long, the organization will have wrung out every one of the investment funds it can and may be left searching for other substantial advantages. The inquiry is, by what other method would we be able to utilize cloud?
  1. The answer lies in a little however developing number of organizations that are beginning to utilize cloud in really problematic ways.
  2. These organizations are breaking into new markets and commercial ventures or making new income streams.
  3. Furthermore, they aren’t the only one.
  4. An IBM Institute for Business Value report titled, “The Power of Cloud,” found that 16 percent of overview respondents are utilizing cloud as a device to advance.
  5. Absolutely taking advantage of the cloud to drive advancement may not be as promptly evident or as simple for organizations as utilizing cloud to lessen altered IT costs.
  6. It obliges constraining organizations to consider cloud in completely new ways.

 

  • Upsetting an industry
  1. Drivewyze, situated in Canada, knows direct about utilizing the cloud to drive development. The moderately youthful organization perceived the business sector need to securely lessen the inefficiencies in the trucking business. With an expected 1.2 million trucking organizations in the U.S. moving Computingalmost 10 billion tons of cargo, the trucking business is frequently alluded to as the nation’s foundation economy. What’s more, with such a great amount in question, keeping up wellbeing on the streets for both trucks and different vehicles is a top need for law implementation offices.
  2. As a major aspect of taking after security measures, truckers should frequently stop at roadside assessment stations which are set up to recognize dangerous vehicles.
  3. An outcome of obliging all trucks to stop, paying little heed to their individual wellbeing records, is that protected trucks frequently confront pointless postponements in conveying their cargo.
  4. While making great time and keeping up an abnormal state of security are both essential objectives to the trucking business, they are objectives that are regularly at chances.
  5. Furthermore, with 4.5 million trucks needed to answer to measure stations in North America and just 13,000 controllers, Drivewyze accepted there must be a superior path for law implementation to lessen unnecessary assessments on safe trucks and concentrate on the dangerous ones.
