IT is no longer a back office, but a board matter and transformed the way business is generated and innovation are operated. Technology has today allows innovative processes and systems – while daily operations including security, end-user applications, data analysis, and more needs to be managed.
Because of the dependence of ever larger amounts of data and the associated loss of business activity, a Disaster Recovery is necessary. A disaster recovery is essential for almost every IT company.
A modern disaster recovery must be based on fundamental components, where one should start with a few basic criteria. The components can be divided into three parts, namely Disaster Recovery-as-a-Service (DRaaS), Network and Managed Hosting.
The first component is DRaaS. DRaaS is a cloud-based service with computing and storage resources to back up data, run applications, to test/simulate and to facilitate the migration of services.
Due to the virtualization technology, Recovery-as-a-Service offers economic advantages over a dedicated DR. DRaaS complements the computing resources of a virtual private cloud, and thus makes it possible to replicate the important data of a company. Since nowadays many applications are managed in the cloud, creates a synergy between disaster recovery and cloud service model is an important aspect.
DRaaS provides following advantages:
- Your data will be securely stored externally
- If virtualization is already used in your data center, a DR can be managed with existing hyper visors and VM management tools.
- The service is available as operating The capital expenditure is limited.
- The DR-effort can be adapted flexibly and easily as needed.
If you are after a DR solution that suits your needs, please check the following points when assessing a provider to determine that these offer an adequate basis for your DR solution:
- Can the DRaaS management be integrated into your current IT management tools?
- How well your data are backed up?
- Where the provider is reliable and can help you in an emergency?
- Is the technology proven?
- Can I choose the location of the data storage and services to manage?
- Are support services available or is much personal contribution necessary?
- If a scaling up or down is possible to be changed requirements?
Compared to an Internet connection, a dedicated connection provides a reliable transmission of data packets, greater security and lower latency.
If you are running DRaaS in conjunction with a virtualized IT environment locally or outsourced, you need a reliable and secure network connection to move data from the disaster recovery services in the cloud. This connection is also required to run the commands for DRaaS test, so as to outsource the event of a failure in virtual machines and run a fallback for the solution.
One possibility for this connection is to a public Internet connection. Most companies have access tothe public internet without having to purchase new hardware. A public Internet connection may not be reliable enough to run a DR test. The bandwidth is busy and may not provide adequate security, which is required for critical applications. A public Internet terminal is favorable and works, but it represents a weak point in the execution of a DR.
An alternative would be to a dedicated DRaaS connection that is used by some providers also known as “Direct Connect”. Under a dedicated connection, it is defined as a stand-alone communications service, which must be ordered.
The most common options for network services are:
Multi Protocol Label Switching (MPLS)
- An IP-based, virtual, private routed network
- A flexible topology with an any-to-any VPN connection
- Using the hardware of the network provider
Virtual Private LAN Services (VPLS)
- An Ethernet-based multi point Virtual Private Network
- A flexible dedicated connections topology
- Using your router hardware
Ethernet Virtual Private LAN (EVPL)
- Virtual point-to-point connection
- Cost leased line over longer distances
- Using your router hardware
The final aspect of the network principle is to connect to a Tier 1 network backbone. If your network providers have direct access to a Tier 1 backbone feature, the throughput and network problems can be managed quickly.
Although most computing services are outsourced to the cloud, managed hosting is an important and sophisticated service. A well-managed hosting environment is the perfect solution for hosting:
- Business applications (email, HR, ERP, Finance, etc.)
- Data Storage
- Websites and web-related services
An advantage of managed hosting is that administrative tasks to hardware, operating systems and software can be outsourced. Hosting can also assist you with a need-based scaling of computing services, storage, power and cooling capacity. Hosting providers offer redundancy and security features that comply with industry standards, so you do not have to worry about anything. The providers work in data centers at different locations, giving you the opportunity to host your infrastructure at an optimal location.
If Disaster Recovery is used in conjunction with managed hosting, the computing resources, applications and data can be stored in the same facility as the DRaaS. This connection does not use Wide Area Network Services and does not affect your public Internet access.
In order to assess managed hosting as a principle in your DR solution, you should have the following points with potential suppliers:
- How many data centers are available? Where are they located? The place is more important than convenience. A nearby location reduces network latency and improves the data duplication. These are the key to DRaaS.
- Which Network Connectivity services are offered? A plurality of network services enhanced access to the hosting site. A provider that operates its own network can offer more options and better manage the connections.
- How is security guaranteed? This includes network security (protection against DDoS attacks, threat detection, etc.) and physical security.
- What support is offered? In addition to space and power, a Service Level Agreements should have defined in terms of support, security, power, cooling, availability, and infrastructure management.
- If DRaaS offered and supported?
A comprehensive disaster recovery strategy is essential for almost all companies. There are different DR options. Disaster Recovery-as-a-Service is a secure and cost-effective option here. The combination of DRaaS with networks and managed hosting services represents an optimum solution for disaster recovery as it offers ease of use, cost-effectiveness and speed.
