Build Your Employee Self-Service Portal With ProActive

 In the past few years, people are consuming more and more services to perform their jobs properly. Managing them is the role of the IT department. However some employees might want to bypass this department to be faster which can create what is called “shadow IT”. Some others might be frustrated at being queued and waiting for additional checks to be performed.

 A solution for this situation needs to balance IT and non-IT needs by providing a user friendly interface which is fast for non-IT (from another department) users and provides governance for IT users. More precisely, this could be achieved by joining all possible applications and services into a single platform. This way, application and service lifecycles can be easily managed and custom templates can be made available for all to use (and create). This would allow for faster and more agile deployment as well as improve governance by giving visibility over the current services and by using a common standard.

 ProActive Cloud Automation offers a solution through a self-service portal to monitor and manage application and service lifecycles. The IT department can easily create templates which follow business policies and could be made available to user groups.

Network State Selection for Data Transfer

 Many applications such as online meetings and video streaming need to transmit large amount of data as quickly as possible. Good signal is consequently required for those transmissions, otherwise you might experience web conferences cutting or video pausing at unexpected time. Other applications need to send content with appropriate quality according to signal strength.

Resource selection based on network properties

 However, the quality of said signal can vary due to external parameters. Fortunately, networks are redundant which allow multiple paths with different properties to lead to the same device. This is why there is a use for flows to pass by carefully chosen resources. This choice may be made according to values such as ping and/or bandwidth.

Cloud Wastes, 7 Recommendations

Accessing new resources has never been easier than today with public cloud providers offering compute power on an hourly based with varying specs such as GPU, RAM, CPU, etc. However, recent articles over the web have come to the same conclusion, companies are wasting money in the cloud.

“RightScale reveals that cloud users could reduce their spend by an average of 35 percent by making better use of resources.” BetaNews
“The benefits of shifting business applications to Web-friendly cloud services is proving far more complex than lining up a partner and flipping a switch” Wall Street Journal
“More and more companies are migrating to the cloud for computing power, but many are actually wasting too much money on unused services.”

To quickly summarize, the main reasons behind these cloud leaks mentioned across these articles are oversized resource, resource not required at all time and algorithm not resource aware.

Resource Reservation

Each IT infrastructure includes heterogeneous resources which serve different purposes. Some resources might be more suited for RAM consuming tasks, other might include a secured database, other offer low latency to the customer and other might have bigger bandwidth.

This article will take as an example the need to access a database or any specific resource for a given task. A selection script will ensure this task will be executed on the server hosting this resource but other requirements have to be considered.
What if there are other tasks waiting and yours has higher priority? What if your task requires the whole capacity of the machine?

Big Data, Languages and Software solutions

Inspired from an article from ThinkR

Big Data is a common term that everyone uses without really having a clear definition of what it is. It is used everywhere and in every industry from transportation, human resources, healthcare, etc. which makes it more difficult to specify. For this article, let’s agree that big data is when it is not possible to handle the information with a single computer even though these days, computers are available with 1Tb of ram. In some more and more common cases, all the data for a computation might not even be in one place which requires advanced distributed algorithms and software.

Big Data for Hadley Wickham

Hadley Wickam well known developer for the R language, who developed multiple librairies used in most projects, defined 3 main categories for Big Data:

ProActive Calendar Step-by-Step

Calendars offer a nice user friendly interface which allow to plan ahead, manipulate events, duplicate them and much more.

By extending traditional applications, more than just events can be handled.

Introducing our calendar service. With this, ProActive Workflows&Scheduling offers more flexibility and a way to automatically synchronize the scheduler with your favorite calendar manager (Google Calendar, Thunderbird, Outlook, Apple Calendar, etc). This offer a new UI adapted for repetitive tasks, enabling more intuitive control through better visualization and simplified job handling (drag&drop). To use our calendar service, navigate to the scheduler, click on “calendar”, retrieve the url (generate it if needed) and use it to create a new calendar. It is possible to test this through our free online test platform.

Risk Model Optimization and Traceability for Solvency II

Solvency II and Basel III, the new standards for insurance and bank regulations, codify and unify capital, data management, and disclosure requirements for insurers and banks in order to protect companies and consumers from risk.

More specifically, with Solvency II the effect of every insurance contract capital market relation, optionally and risk source has to be modeled and measured. The goal is to ensure insurances have enough equity to cope with any forecasted risk. Considering the amount of heterogeneous assets and liabilities owned by an insurance company, algorithms such as Monte Carlo are suitable to estimate the result of different scenarios with a given accuracy and get metrics such as VaR (value at risk).

A typical process using a Monte Carlo algorithm regularly involves multiple steps:

  1. Defining a model for each asset, liability, economic scenarios, etc. using tools such as Quantlib, Bloomberg solution, Wall Street system, Apollo, etc.
  2. Create scenarios based on these models (It can easily go above 2 millions scenarios)
