The nearly wholesale transition to cloud computing in application deployment is a trend that has been impossible not to notice in recent years. But while the trend makes it clear that there are benefits to application cloud migration, not every application will succeed in the cloud.
There are several compelling reasons you may want to consider “SaaS-ifying” your enterprise applications:
But before you begin preparing your application for migration, there are a few points you should consider.
Can you manage SaaS?
It is important to understand that in the process of migrating an enterprise application to a SaaS service, it essentially becomes a product. And like any product, it must be effectively managed and supported. This means roadmaps, marketing, support, etc. If this will not be possible for you, you may need to rethink whether to migrate this particular application.
Is the application ready for a SaaS transformation?
Applications and related services designed for internal use are not usually built to run on SaaS solutions, and may be less complete and robust than a client-facing application. Depending on the current state of your application, you may need to invest significant time and effort in refactoring the application and its resources. In the worst cases, significant portions of the application and its supporting resources may need to be restructured or rewritten.
The difference between multiple users and multiple instances
An application designed for internal use is often built to support many users, but rarely to support many instances. While in its current state, it is sufficient to run one instance of the application and its resources with all the users connecting to that instance. SaaS deployment will require your application to be able to run multiple instances, each with their own space and resources. This often requires a new way of thinking about the application in order to keep each instance virtually distinct and separate while allowing them to simultaneously access hardware resources.
The security of your application and its data is a crucial concern and deploying your application in the cloud opens it up to new vulnerabilities. You will need to make sure that you have taken all the necessary measures to keep your sensitive and critical data safe from malicious third parties, catastrophic data loss and system failure, in addition to service outages.
As SaaS migration removes an enterprise application’s geographical limitations and allows its use to expand globally, your application may become subject to different legislation, regulations, and industry standards. A notable example is the European General Data Protection Regulation adopted in 2018. You may need to invest significant time in ensuring that you are complying with all relevant regulations and standards pertaining to your application’s functionalities.
SaaS-deployed applications will likely run on public cloud IaaS services. The cost of these IaaS services needs to be considered in your operations cost projections. You will also need to account for the personnel needed to effectively operate the application and provide user support and service.

What Is an SQL Query Engine? SQL query engine architecture was designed to allow users to query a variety of data sources within a single query. While early SQL-based query engines such as Apache Hive allowed analysts to cut through the clutter of analytical data, they found running SQL analytics on multi-petabyte data warehouses to be a time-intensive process that was difficult to visualize and hard to scale.Explore

Engage Your Workforce with a Modern Employee Intranet Solution The employee intranet has changed significantly since it was first introduced in the early 1990s. What started as HTML-based static portals have now evolved into intuitive communication tools complete with search engines, user profiles, blogs, event planners, and more. Today, many organizations are taking a second look at employee intranets to bridge gaps between teams, build company culture, centralize information, increase productivity, and improve workflow.Explore
Adopting emerging cloud technologies, consolidating resources, and improving processes is the key. “IT no longer just supports corporate operations as it traditionally has but is fully participating in business value delivery. Not only does this shift IT from a back-office role to the front of business, but it also changes the source of funding from an overhead expense that is maintained, monitored, and sometimes cut, to the thing that drives revenue,” said John-David Lovelock, research vice president at Gartner.Explore
Deliver Powerful Insights Instantaneously with Federated Queries - No Matter Where Your Data Resides The concept of federated queries isn’t new. Facebook PrestoDB popularized the idea of distributed structured query language (SQL) query engines in 2013. Over the years, AWS, Google, Microsoft, and many others in the industry have accelerated the adoption of a distributed query engine model within their products. For example, AWS developed Amazon Athena on top of the Presto code base, while Google’s BigQuery is based on Cloud SQL.Explore
What is Unstructured Data? Almost 80% of the data that enterprises and organizations collect is unstructured - data without a set record format or structure. Unstructured data includes data such as emails, web pages, PDFs, documents, customer feedback, in-app reviews, social media, video files, audio files, and images.Explore
