Luciano Alencar e Silva

Infrastructure Manager

“The HTI team has been managing our SQL Server servers for the past 6 months. When we hired them, we made our frustrations with the previous service provider clear, as well as our expectations for the new contract. During this period, the number of incidents has decreased significantly, thanks to the preventive actions and adjustments they recommended and implemented. We moved from an uncertain scenario with many sleepless nights to a stable and reliable environment. In the one serious incident we experienced, the SLA was exceptional. It has been a continuous and hard work of adjustments, but to date, we are very satisfied with the choice we made. Great job, team!”

Alex Paulo Manzo

IT Manager

“We were facing issues due to ransomware in our network, and HTI Tecnologia helped us with the ESET solution, which led to the acquisition of 594 licenses. Thanks to this great work, we were able to avoid numerous disruptions caused by the vast range of cyber threats that exist and disturb the peace of IT professionals, affecting both public and private sectors. I express my deep gratitude to HTI Tecnologia for their commitment, seriousness, and professionalism in handling our case. Even without the guarantee of a purchase (as we are a public institution), they never refused to provide all the necessary attention required for the situation. I would also like to thank them for the excellent post-sales support and prompt assistance, which contributed to the successful implementation of this renowned solution in the market.”

Marcela Souza Diniz

Systems Manager

“I would like to formally express our gratitude to HTI Tecnologia for the promptness, professionalism, and speed with which our case was handled. Due to a series of factors, we had to migrate our Oracle servers to MySQL. Operating under the common assumption that a database is just a database, we carried out the migration on our own. However, after exceeding the limits of Oracle Standard, we were faced with a slow, unstable system and a database full of surprises. With no budget to return to Oracle, now in its Enterprise version, we found ourselves in a dead end.

We were referred to HTI and decided to hire them as a last resort before seeking funding to invest in hardware and software. They approached our critical situation with good humor and even optimism (which I must point out). In just two weeks of consulting, we discovered two key things: that databases can be very different from one another, and that MySQL is indeed a viable option for large-scale databases.

With unmatched professionalism, HTI Tecnologia tuned our servers from the operating system to MySQL. They helped us rewrite some SQL queries and even provided valuable insights into database modeling and application design.

Thank you very much, truly! Wishing you lots of luck and success in 2016!”

Mariano Andrade Martins

“Our company has been using MySQL as its primary database for at least five years. All the database tuning and modeling was done in-house. Both the company and users have been satisfied with MySQL.

Recently, the company acquired *******, a BI tool designed to run natively on MySQL. We purchased new ********* servers for this purpose, which initially performed above expectations. However, once we reached full application load, it became impossible to generate any type of report, from the simplest to the most complex.

HTI played a key role in helping us resolve this issue. By installing special engines optimized for BI, we were able to provide our users—mostly managers and directors—with the information they need, without having to wait hours for a report.”

Luiz Evangelista Ruiz

Systems Manager

“Our company specializes in generating knowledge based on user behavior. We started building our database in MySQL five years ago with HTI’s help. As ‘Uncle’ says, we were swept up by Big Data. With the rapid growth of our databases, our diagnostics, forecasts, and other reports stopped running—or when they did, they took more than 15 hours depending on the selection criteria. This was despite applying several MySQL scalability techniques.

Once again, we turned to HTI and ‘Uncle.’ With our current OLAP database reaching 10TB and still growing… we adopted a Hadoop solution with a small cluster. The total investment in the project, including HTI’s consulting and servers, was just 10% of the cost of licenses for the commercial product we had considered. Today, all our reports run with performance exceeding expectations.

Once again, HTI and ‘Uncle’ saved us. As a former student and a client, I feel very comfortable giving this testimonial, because HTI has truly been a zoo of solutions—from Dolphins to Elephants. In my humble opinion, HTI is the most specialized and, above all, the most responsible company when it comes to databases, whether it’s MySQL, Hadoop, or any other ‘creature.’ More than just giving my testimony, I want to leave a heartfelt thank you.”

Alexandre P Schutz

Director

“It was a difficult decision to hire a company to work remotely on the database of our main client. We are pleased with the professional manner in which HTI served both us and our client.”

João Paulo Silva

Project Manager (Database)

“The bank decided to adopt the LAMP platform for its home-broker initiative. Everything went smoothly until the number of accesses—and consequently, the database—started to grow. We hired HTI for a mentoring process. Today, our home-broker solution is a success story within our bank.”

Humberto Silveira

Senior Java Developer

We are a company that provides VOIP services. We needed to find an efficient and low-cost solution for billing & invoicing, and ideally, one that integrated with Asterisk. After the mentoring provided by HTI, we were able to easily integrate ERP + Asterisk + MySQL. We are very satisfied with the service provided to us.

Adriano Siracusa

“We are wireless internet service providers in the state of Rio Grande do Sul. We use the MySQL database to manage user access (authentication), usage, traffic, among other things. We faced a serious issue early this morning and decided to try HTI’s emergency service. To be honest, I didn’t believe it would work.

In less than 30 minutes, I received an email with contact information via phone or Skype. After granting access to the HTI technician, it took no more than an hour to fully restore our authentication service, which had been down.

It’s great to know we have this kind of 24/7 service available in Brazil. I want to express our sincere thanks here, and we’ll definitely be joining HTI for DBA training.”

Roseanne Paixão

Oracle/MSSQL DBA

“We had tried several approaches to solve our database problem: blogs, forums, specialized books, training courses, and ‘consulting services.’ We were already set on purchasing a **** database when we received a direct mail piece from HTI. Seven months of failed attempts were summarized—and resolved—in just one week.

We are grateful to HTI not only for the financial savings they provided, but also for the significant reduction in manpower and the headaches that a migration at this stage would have caused. We are satisfied with our MySQL. HTI is definitive when it comes to MySQL.”

Roney Medice

Hiper Export S/A, Vila Velha

“We have been using Escan Enterprise since 2009 and are very satisfied with the product. With the Escan solution, we have managed to reduce spam by over 85%.”

Michael Gallo

“We were looking for a high-availability solution for our online booking application—one that didn’t rely on dedicated hardware, offered high performance, and kept costs low. After several in-house attempts, we decided to bring in a more experienced consultancy that could make it all happen within a defined timeframe and without trial and error.

We hired HTI, and they made it possible using well-known tools. In just one week, our MySQL databases and web servers were fully redundant, with exceptional performance.”
