The company wants to ensure its business is always operational, even in the case of a disaster affecting the primary site. The disaster recovery site is located 100 miles away, which implies that the company is looking for a site that can quickly take over operations with minimal downtime and without requiring significant manual intervention.
There are several types of disaster recovery sites that the company could implement, each with its advantages and disadvantages. The most suitable type of disaster recovery site in this scenario is a hot site.
A hot site is a disaster recovery site that is fully operational and has all the necessary equipment, infrastructure, and data in place to take over the primary site's operations immediately. This type of site provides the least amount of downtime and requires minimal manual intervention to switch over to the secondary site. The cost of a hot site is usually high due to the high level of redundancy and the need to keep it operational continuously.
A warm site, on the other hand, is a disaster recovery site that has some of the necessary equipment, infrastructure, and data in place but is not fully operational. The company would need to install additional equipment and restore data to make it fully operational. This type of site has a higher downtime than a hot site but is less expensive.
A cold site is a disaster recovery site that has basic infrastructure, such as power and cooling, but does not have any of the necessary equipment or data in place. The company would need to install all the necessary equipment and restore data to make it operational. This type of site has the highest downtime and is the least expensive.
A cloud-based site is a disaster recovery site that uses cloud services to replicate data and applications. In this scenario, the company would need to ensure that the cloud provider's location is far enough away from the primary site to avoid being affected by the same disaster. This type of site has a moderate downtime, and the cost depends on the amount of data and services that need to be replicated.
In conclusion, a hot site is the most suitable type of disaster recovery site for the stock trading company as it provides the least amount of downtime and requires minimal manual intervention to switch over to the secondary site.
