Highly available data center in Munich: How to minimize downtime and protect your business

What distinguishes a highly available data center?

A highly available—or fail-safe—data center remains online even in the event of power outages or technical malfunctions. We rely on consistent redundancy, failover mechanisms, and state-of-the-art technologies to achieve availability levels ranging from 99.99% to 99.999% (“five nines”). Specifically, this means:

• Redundancy of all core components: Power supply, cooling, and network (at least N+1).
• Disaster recovery plans: Regular emergency tests and drills increase reliability.
• Scalable architecture: New IT resources can be added during operation.

For companies in and around Munich that need to be available around the clock, high availability is at the heart of their IT infrastructure. In addition, a certified data center makes it easier to comply with regulatory requirements (e.g., GDPR).

Important Certifications and Tier-Level

The Uptime Institute defines four tiers that specify exactly how fail-safe and maintenance-friendly a data center is:

• Tier 1: Basic infrastructure without redundancy – insufficient for business-critical applications.
• Tier 2: Partial redundancy; maintenance often leads to restrictions.
• Tier 3: N+1 redundancy, maintenance without interruption, high availability.
• Tier 4: Highest reliability (2N+1), fault-tolerant in all areas.

Even a Tier 3 data center offers a very high level of operational reliability. However, industries with extreme availability requirements often need Tier 4 availability. Supplementary standards such as ISO 27001 or EN 50600 ensure that even the most stringent requirements are demonstrably met.

1. Avoidance of high costs and damage to image

Even short downtimes can cause massive losses in revenue, result in insurance claims, or permanently damage the trust of your customers. A consistent high-availability strategy ensures that your services remain accessible at all times.

2. Security and Compliance

Highly available Data Centers offer security measures such as access controls, video surveillance, and modern fire suppression systems. This reduces the risk of unauthorized access and physical damage, while also ensuring compliance with key regulations.

3. Scalability and Flexibility

With colocation solutions, you can expand or reduce IT resources as needed, thereby mitigating availability risks, for example during temporary peak loads. This saves costs and allows you to respond to market demands without lengthy conversions.

1. Location selection and connectivity

• Location redundancy: First, clarify whether IT should be operated at one or two locations.
• Network redundancy: At least two independent, separate data lines—ideally from different network providers.
• Power supply: Multiple, monitored circuits, UPS systems, and emergency power generators with direct connection to substations.
• Comprehensive risk analyses: Transport links, flood protection, and other local factors must be evaluated.

2. Redundancy concepts

We use N+1, 2N, or 2(N+1) depending on requirements. At our Munich campus, we operate two separate data centers, MUC I and MUC II, with local site redundancy.

3. Virtualization and cloud connectivity

Many customers use hybrid cloud scenarios to distribute resources flexibly and accelerate failover processes. A second data center or public cloud integration enables highly available operation without downtime.

Practical examples: How companies successfully utilize high availability

• Sportec Solutions AG: processes around 65 million live data points per Bundesliga round. Thanks to our highly secure data center infrastructure and redundant supply routes, the company can provide real-time analyses without any downtime.
• InterNetX GmbH: doubled its data center capacity with an additional private data center. Redundant security zones, dual power supplies, and fail-safe network connections across multiple data center areas significantly increased the performance of its IT.
• Artcodix GmbH: operates highly available, GDPR-compliant cloud infrastructures for universities. Mirroring at two geo-redundant data center locations in Munich and Rosenheim ensures maximum reliability and availability – “Bavarian redundancy” ensures low latency and maximum data security.

Sustainability as a competitive advantage

Our data centers focus not only on high availability, but also on environmentally friendly solutions. As part of the Climate Neutral Data Centre Pact, we are continuously working to operate our infrastructure in a climate-neutral manner. Since 2012, we have been using only renewable energies and highly efficient, climate-friendly cooling technologies. This enables us to reduce our carbon footprint and help our customers save operating costs and meet the growing demand for green IT solutions.

Common mistakes and practical advice

• One or two locations, insufficient redundancy?
• It is often unclear whether IT systems should be operated at only one or two locations. Before any planning takes place, it must be clarified whether a single location is sufficient, what technical redundancies exist there, or whether geographical separation is necessary.
• Underestimating location factors: Risks such as flooding or traffic networks are often given too little consideration.
• Lack of DR testing: Test emergency procedures regularly to ensure that failover and recovery work smoothly.
• Forgetting to scale: Plan for growth reserves so that your data center provider can provide sufficient resources in the future.
• Not prioritizing IT security: High availability and comprehensive security must go hand in hand.
• Non-transparent SLAs and lack of monitoring: Clear service level agreements, defined response times, and automated monitoring are essential.

How much does a high-availability data center in Munich cost?

The question “How much does a high-availability data center in Munich cost?” can only be answered on a case-by-case basis. Relevant factors include:

• Technology and equipment: Redundant power supply, UPS systems, air conditioning, and much more
• Certification and redundancy (Tier 3 or Tier 4): Higher security levels require greater investment.
• Location factors: Rental and energy costs vary in Munich and the surrounding area.
• Staff and service level: 24/7 support, maintenance, and security personnel.

Make or buy? Availability comes at a price. It is often more economical to use colocation services than to set up your own Tier 3 or Tier 4 data center. You retain full control over your IT—we take care of infrastructure, security, and availability at contractually defined, transparent costs.

Conclusion

As EMC Home of Data, we support companies in setting up and operating highly available data centers in Munich, Bavaria, and throughout Germany. With many years of experience, we combine technical redundancies, disaster recovery concepts, certified security standards (Tier 3/Tier 4), and sustainable technologies.

Those who cannot accept downtime gain a decisive competitive advantage with a well-thought-out high-availability strategy and modern colocation infrastructure – whether they are a start-up or a large corporation.

In this way, we create the conditions for maximum availability for our customers.
