Reference: https://searchdisasterrecovery.techtarget.com/definition/hot-site A hot site is what would best meet the requirement of ensuring all production capabilities are available within two hours for a disaster recovery solution. A disaster recovery solution is a plan or process of restoring normal operation and performance of a system or service after a disruption or disaster. A disaster recovery solution can use different types of sites or locations to store and recover data or resources, such as:
A hot site: This is a site or location that has a fully operational and ready-to-use replica or copy of the original system or service, including data, resources, applications, etc. A hot site can provide benefits such as:
Availability: A hot site can provide availability by ensuring that the system or service can be switched or transferred to the hot site immediately or within minutes after a disruption or disaster, without any downtime or interruption.
Capability: A hot site can provide capability by ensuring that the system or service can function and perform at the same level or quality as the original system or service, without any loss or degradation.
A warm site: This is a site or location that has a partially operational and ready-to-use replica or copy of the original system or service, including some data, resources, applications, etc. A warm site can provide benefits such as:
Affordability: A warm site can provide affordability by reducing the cost of maintaining and updating the replica or copy of the original system or service, compared to a hot site.
Flexibility: A warm site can provide flexibility by allowing customers to customize and configure the replica or copy of the original system or service according to their needs and preferences, compared to a hot site.
A cold site: This is a site or location that has no operational and ready-to-use replica or copy of the original system or service, but only has the necessary infrastructure or facilities to support it, such as power, network, space, etc. A cold site can provide benefits such as:
Scalability: A cold site can provide scalability by enabling customers to expand and grow their replica or copy of the original system or service as needed, without any limitations or constraints.
Security: A cold site can provide security by minimizing the exposure or risk of the replica or copy of the original system or service to any threats or attacks, compared to a hot site or a warm site
