Companies We’ve Helped

Impressed with the responsiveness and professionalism

We initially engaged Red9 to troubleshoot a series of ancient SQL databases that had come to a crawl and become a major pain point for our client. Red9 dove in head first optimizing the databases, auditing the results, and once the situation was stable, advising on a strategy for moving forward.

Before taking the first job, Red9 talked us through the issues we were having to ensure Red9 was right for the job. It was clear from that first project that they are incredibly skilled and knowledgeable. On top of the aptitude offered by Red9 DBAs, I've been and continue to be impressed with the responsiveness and professionalism that we've come to count on at Red9.

60% decrease in CPU

On an urgent SQL issue, Red9 DBAs did a great job.… With little notice Red9 was able to find and fix a number of different SQL misconfigurations and wasteful practices. After a weekend of work, the customer realized a 60% decrease in CPU utilization as a direct result of Red9's work.

Even under 5,000+ concurrent connections, Red9 keeps us running smooth

Red9 are the experts in large scale MS SQL Database environments which exceed 5,000+ concurrent connections. They have mastered the understanding of complex, heavy load TSQL transactions. When tuning, database structure, indexes, stored procedure, best practices, up-time, and smooth performance are all important, Red9 is the type of DBA company who truly knows how to keep these high standards. If you are growing your feature sets centered around MS SQL, then developers will benefit greatly from Red9's time to more efficiently write code. If you would like to sleep better at night and know your database will be running well in the morning, then I would recommend finding a DBA company with the kind of skill set Red9 has proven time and time again.

Highly regarded SQL database expertise

It has been a great pleasure working with Red9. From the get-go I could tell Red9 SQL DBAs knew what they were talking about, and put my mind at ease. We will be using Red9 going forward for everything database related. I would highly recommend Red9.

Always willing and able to resolve our issues

We do not have an inhouse database administrator, Red9 is now our database admin!! Reliability and knowledge – Red9 is very knowledgeable about SQL and was able to put a project together for us in very short amount of time. When we need any assistance, they are always willing and able to resolve our issues within a reasonable time! I am not sure you will find anyone else that can perform as well as Red9! I don’t think there anything they cannot handle from a SQL perspective.

Significant performance improvement in minutes

In just a few minutes, Red9 was able to find significant performance improvement opportunities in our database. These improvements were in areas we hadn’t even considered. Red9 came up with many ideas; just the top 2 to 3 were enough to give us a significant performance boost. Red9 DBAs have extensive knowledge when it comes to SQL Server. I can’t imagine there is anything they don’t know. We plan to continue to work with Red9 on a regular basis and continue to enjoy the benefits of their knowledge.

Fixed in 30 min, what others could not do in 3 weeks

Red9 is UNBELIEVABLE! We had a server connection issue plaguing us for over 3 weeks. We had 2 so-called professionals trying to figure out what the problem was, and after 3 weeks they were still scratching their heads! We hired Red9 to investigate this issue. Within ONE HOUR Red9 DBAs honed-in on the actual problem; advised us on what needed to be done with the Server Hosting company, and then within 30 minutes we finally had access to the crucial data we needed to run our business! Anyone looking for a TRUE professional regarding SQL or SQL Server, don't even bother looking elsewhere; Red9 is the exactly the company you want and need!

Extremely helpful

Red9 provided DBA was an expert, accurate, extremely helpful, and could not say enough positive things about their level of skill and ability to understand the issues at hand and explain both at a high level and with intricate attention to detail. Will definitely hire again.

Great deal of experience with performance monitoring!

Red9 has a great deal of experience with performance monitoring management inside of SQL, which was super critical for us. Our client was experiencing performance issues because a third-party vendor was implementing software sub-optimally on the infrastructure we implemented and hosted. We engaged Red9 for senior SQL expertise to evaluate and fix the problem. Red9 did a deep performance assessment, identified that the problem was in the software implementation and what improvements were needed, implemented those improvements, and then measured and documented the difference in performance. Because of Red9, we were able to show our client the root cause of their problem and the quantifiable difference it made for their business after the problem was fixed. Beyond deep technical expertise, communication is very important to us. Red9 was timely in responses, met set expectations and timelines, and kept us in the loop when an unexpected issue came up. I would absolutely recommend Red9.

Outstanding!

You're the best. When I think of how long you guys stood by waiting for this work to happen, and then when it did, the Client was so pleased. Red9 SQL resources were highly skilled DBAs and I'm sure the work we are having them do is far below their qualifications…

The single biggest benefit has been performance gains and tuning associated with migrating to AWS and a newer version of SQL Server with Always On clustering. Red9 was an integral part of this process. Red9 has incredible expertise both in SQL migration and performance tuning. The deep level of knowledge of MSSQL is incredible and the combined experience and expertise has been a huge asset. Additionally, the flexibility and professionalism throughout a difficult migration was highly appreciated. If someone is was on the fence about choosing Red9 as their SQL Server Support firm, I would suggest they setup a call with one of the SQL experts at Red9 and get a performance assessment. Red9 was able to find a number of inefficient indexes and performance bottlenecks that resulted in over 400% improvement in latency.

If you're running MS SQL Server, do yourself a favor and give the Red9 team a call.

The Red9 SQL DBA team is outstanding at what they do.

The Red9 SQL DBA team is outstanding at what they do. We found red9 DBAs trustworthy for all database reliability and speed optimization needs. I have seen them do wonders and would recommend them in a heartbeat for any database need.

The single biggest benefit was Red9’s ability to identify and resolve major pain points

Before we received SQL services from Red9 we were dealing with many major performance bottlenecks with our main business application, and due to being one of the largest clients of our application provider they were not able to dedicate the resources to resolving the issues we experienced. Not to mention that without an in-house SQL Server expert we couldn't guarantee that the problems were database related and not hardware or configuration related. Red9 first gave us the overview of where our difficulties were coming from. We were able to identify what specifically needed to be resolved by the app developer and what could be resolved by ourselves. Then Red9 offered to get on a conference call with our app developer and walk through the issues with them as well. The single biggest benefit we saw when working with Red9 was their ability to identify and resolve major pain points in conjunction with the app developer quickly and effectively. We still have a ways to go but we are confident that Red9 will be a long term partner for our business.

Exceptional Service

Since partnering with Red9, we've seen significant improvements and proactive optimizations in our system. The team's expertise and exceptional service make them an invaluable partner. Highly recommend Red9 for anyone in need of top-tier database management!
