Migrate Legacy Application To Multi-Tenant Cloud Based Application
Is the real future Multi-Tenant Cloud based application? What is the true path to illumination Multi-Tenant architecture or single-tenancy? Is Multi-Tenant architecture truly “faster-better-cheaper”?
The answers to all of these have been looked upon in this article. Let us first understand a few basics.
What is Multi-Tenant architecture?
Multi-Tenant architecture is a software architecture where a single instance of the software runs on a server and serving multiple client organizations (tenants). The architecture of the software is built as such that it separates software instances for different tenants or customers i.e. it virtually separates its data and configuration for each customer making it customized in nature. Its also an indispensable attribute of cloud computing.
How is Multi-Tenant architecture different from single-tenant systems?
In Single-Tenant architecture, as the name suggests, the software can be tailored for each tenant separately. The system houses the data for each company on a separate server. Each tenant runs its own copy of the software. The separation can be either virtual (virtual machines on a same server) or physical (running on separate machines).
In a Multi-Tenant Cloud based application, the data from multiple companies are placed on the same server generally separated from each other via a simple partition that prevents data to migrate from one company to another. As the data is housed on the same server, each company using the software is running the same basic application, with the same basic functionality and with the same limited configuration capabilities.
What are the potential challenges of migrating into Multi-Tenant architecture?
In many instances the capacity requirements of a small tenant could go below the minimum capacity database thats available. There is an invariable cost to a database and a smaller database does not perk up much in cost to provide benefits.
In cases of larger tenant count, organizing huge independent surfaces leads to issues. While handling thousands of tenants, thousands of databases needs to be created for them so operations scoped globally to address all the data such as schema deployments or queries that need to report size usage per tenant across all databases would take extremely longer durations to work out.
The applications compatible with much larger databases end up creating connection pool fragmentations. Since every server has a single connection in each pool pointing to the individual database that encloses every tenant, so these connections tend to go cold if every application server does not constantly get a request for each tenant recurrently. In such situations the application finds no connection in the pool and hence needs to start the connection all over again creating performance issues.
How does SaaS overcome the challenges?
SaaS loaded with numerous advantages over the legacy applications presents dramatic changes to both the migration and the delivery of the software solution. Some of the key benefits listed are:
SaaS dynamically allows adjusting the number of tenants per database at any moment in time.
Intense packaging of tenants is possible as one is not trapped with a stagnant tenant layout. With this an affordable and dynamic tenant model is available that can regulate increasing workloads in each tenant.
A major advantage with SaaS is it results in cost savings by merging IT resources into a single operation. Since an application incurs an amount of memory which is sizeable when in proportion to many customers, SaaS reduces this operating cost.
SaaS enables data mining. Instead of collecting data from several sources with diverse database schemas, all the data gets saved in a single database schema. As a result, managing queries across customers, mining data, and looking for trends is much simpler.
Improved usability, custom user Interface and branding.
SaaS abridges the release management process as packages containing code and database changes are required to be installed on a single server.
On the whole, SaaS provides an improved deployment of hardware resources and an enhanced simplicity of maintenance, resulting in lower overall application costs. This makes the technology smart for service providers aiming the small and medium enterprise (SME) business segment.

How you should delete the Hard Drive and the OS, to prevent private data recovery after PC disposal?
You might ask me: Why would I need software, to delete the hard drive even after PC formatting and Recycle Bin emptying for a simple PC disposal? And then you would try to reason with me by saying: It does not cost me anything, it is safe and it is simple, why would I want to waste my money in something I can do it alone? The answer is very simple, because just by doing that; I could recover everything you have entered in your computer!
Knowing how to handle confidential data and personal information such as bank account number, financial data, bank card number and private information is an essential precaution you have to take, in order to protect your privacy against information leakage or theft. Many people believe that just by formatting their PC hard drive will remove all of their input information. The truth is that, the deleted file on your screen does not get completely erased on the hard drive. File traces are digitally left behind on the OS, making the thief’s job less than simple, to recover your confidential data that was supposedly deleted. Of course it is simple and does not cost anything, but really, are you going to take that chance? Think again for a few seconds, and you will know, because I know! You need to have the hard drive deletion software.
What I would recommend you, PC user, is to try out the SECUDRIVE Sanitizer Free for free! They just launched the SECUDRIVE Sanitizer Free for you to experience a safe home PC disposal, without any of your confidential data getting leaked. SUCUDRIVE Sanitizer Free uses the Constant Number deletion mechanism, in which the entire sector is overwritten once by a predetermined constant value. What does that mean? It simply means that your recycle bin or your confidential data will get totally wiped out using the algorithm to overwrite the data that were input into your PC hard drive. This deletion mechanism makes all of the traces left behind by a file unrecoverable and completely deletes the digitally stored data in the hard drive, thus, preventing data loss and confidential information recovery after PC disposal.
And there is one more feature that SECUDRIVE Sanitizer Free presents to the user, the capability of the software to detect bad sectors and efficiently delete the hard drive until completion. SECUDRIVE Sanitizer Free adopted the automatic deletion mechanism to completely delete all of the data and file traces, giving the user a safe hard drive disposal at home. Compared to other hard drive deletion software, that requires you to make a decision every time a bad sector is found or make you wait for hours just to get you disappointed with an error message in the end, SECUDRIVE Sanitizer Free makes the deletion process until completion! When a bad sector is detected in the hard drive by this software, SECUDRIVE Sanitizer Free (deleteharddrive.net) automatically skips the sector until the total deletion of the hard drive is complete. This efficient deletion software obviously, leaves no traces of previous files or input data whatsoever. And that, dear PC user, is how you delete the hard drive completely. Giving you the full confidence that your personal information will be kept and that other confidential data will be kept private after disposing your old PC.
So that is my main concern for you, PC user, that you would remember to delete the hard drive with the appropriate deletion software. And stop using simple deletion tactics to later undergo the experience of having confidential or financial information theft.
SECUDRIVE Sanitizer Free is the software for you, PC user, to have full privacy after disposing of your PC. This software, SECUDRIVE Sanitizer Free, was given as a small door for the user who wishes to stop worrying about confidential data loss or financial information theft after PC disposing.
