Backup and Restore Improvements

by Gethyn Ellis | April 2014 | Enterprise Articles

The lines between on-premise and public cloud services have become blurred. The integration between on-premise and off-premise technologies imply that you can now easily implement a backup solution that makes use of both, thus allowing you to maintain up-to-date backups both on-site and off-site. This will allow you to implement a disaster recovery plan that meets strict service-level agreements without having to invest in a Disaster Recovery (DR) site. The DR site can be in the cloud. Depending on your environment, this can significantly reduce the cost of implementing a fully blown disaster recovery site or server room.

There are several new features in SQL Server 2014 that make this possible; they are as follows:

  • Backup to URL

  • Backup to Microsoft Azure

  • Encryption

In this article by Gethyn Ellis, the author of Getting Started with SQL Server 2014 Administration, you will look at how you can make use of the new features and integrate them into your backup and recovery plans to ensure that you maintain up-to-date off-site backups.

Monte Carlo Simulation and Options

by Yuxing Yan | April 2014 | Open Source

In this article by Yuxing Yan, the author of Python for Finance, discusses how to use Monte Carlo simulation to price European, American, average, lookback, and barrier options.

In finance, we study the trade-off between risk and return. The common definition of risk is uncertainty. For example, when evaluating a potential profitable project, we have to predict many factors in the life of the project, such as the annual sales, price of the final product, prices of raw materials, salary increase of employees, inflation rate, cost of borrowing, cost of new equity, and economic status. For those cases, the Monte Carlo simulation could be used to simulate many possible future outcomes, events, and their various combinations. In this article, we focus on the applications of the Monte Carlo simulation to price various options.
