Streaming & IPTV infrastructure deployment for the first & only automotive TV channel in Ukraine Image

Streaming & IPTV infrastructure deployment for the first & only automotive TV channel in Ukraine

Our client is the first and only Automotive TV channel in Ukraine. They came to us with the request to review their out-dated infrastructure and make necessary changes to update their streaming abilities and improve performance.

Solution

1. Our DevOps team executed full restructuring and redesign of IT infrastructure and automated the provisioning of the backend

services.

2. We partnered with the telecom provider Cosmonova to organize the transition from satellite to IPTV and implemented HD quality in a scalable and cost-effective manner.

3. Configured and integrated real-time, multi-channel IPTV encoders to support various encapsulation formats and significantly increase the content hours delivered. 

4. The next step was to integrate Nagios monitoring system to monitor multiple infrastructure parameters, including uptime, load average, CPU status, process counts, and other.

5. And lastly, we built and deployed a backup system to ensure rapid and reliable disaster recovery.

Project challenge

Regular Internet interferences resulted in unstable TV signal on a regular basis. We build fault tolerance trunk with master and slave link. When the main connection fails, the reserved link automatically routes commercial traffic.

Architecture & infrastructure redesign, Kubernetes integration for the first Ukrainian automotive online market Image

Architecture & infrastructure redesign, Kubernetes integration for the first Ukrainian automotive online market

Our client is the first and the biggest in Ukraine automotive online market. The company connects individuals who want to sell and buy cars on the web platform. The client wanted us to assist with a wide range of infrastructure-related tasks to help streamline their performance and availability.

Solution

We redesigned our client’s architecture, rebuilt infrastructure, documented all the

processes for their technical department, and keep supporting the project. The major steps were:

1. First of all, our DevOps Engineers performed a full audit of the infrastructure and classified major growth areas, bottlenecks, and possible risks.

2. The next step was to create Kubernetes cluster partially distributed between three DC providers: AWS, GCP, and Hetzner, that resulted in high reliability and cost efficiency.

3. To ensure 365/24/7 performance monitoring and risk mitigation, we designed and implemented centralized log gathering system based on ELK stack.

4. We also deployed and integrated corporate mailing system sending 30,000 emails per hour.

Project Challenge

The platform had just a huge amount of images (static content) that had to be immediately displayed on the web pages. To make this possible, our DevOps team designed and deployed own content delivery network (CDN) based on the open-source photo thumbnail service Thumbor и Amazon platform.

High-load high-availability platform development for the first in Ukraine agro-industrial retailer Image

High-load high-availability platform development for the first in Ukraine agro-industrial retailer

Our client is a big agroindustrial retailer offering all kinds of agricultural machinery, sowing material, fertilizers, and other related product to its customers. Previously doing this offline, our client decided to establish an online presence and asked us to build the platform from scratch.

Solution

1. After careful analysis and prioritization of business requirements, we decided to&nbsp

;build the platform based on Tamaranga DO framework, that is optimized for high traffic and has flexible APIs.

2. We adapted the framework for the specific needs of the client’s business and integrated payment systems, including LiqPay, Fondu, and Wallet One.

3. To be fully ready for a massive ad campaign and subsequent traffic increase, we built and deployed a high-availability Kubernetes cluster on AWS with Kops.

Project Challenges

It’s pretty often that farmers live in the areas with a slow Internet connection, so we had to optimize the platform for a low-speed network. We reduced page size and thereby increased page speed, making the platform really simple and really productive.

Another challenge was a huge database with too many slow queries. To overcome this we decided to integrate a high-load MariaDB database. We implemented cache feature and integrated high availability Percona XtraDB Cluster.

Microservices architecture & application clusterization for a Berlin-based fashion e-commerce platform Image

Microservices architecture & application clusterization for a Berlin-based fashion e-commerce platform

Our client, a big e-commerce platform, experienced difficulties with its application availability.

The application hasn’t been optimized to operate as a high-load, high-availability solution and was unable to handle the high traffic.

Solution

1. Our DevOps engineers rebuilt the monolithic architecture into the microservices, making the system more flexible and

eliminating bottlenecks.

2. Built Kubernetes cluster on bare metal servers, implementing high-availability master nodes, scalable networking, Ingress, and persistent storage.

3. Integrated CI/CD pipelines with zero downtime to make app deployment quicker and error-proof.

4. Deployed CI/CD runner with concurrency features to prevent time-consuming tasks from impacting app performance.

5. Integrated four stages of development: dev, test, stage, prod to allow phased, risk-free rollout.

Project Challenges

Client’s budget was limited and cost saving was a priority. We significantly reduced manual work that allowed for headcount reduction.

More specifically, CI/CD implementation reduced HC by 2 due to the automation of manual processes. This diminished human factor and got rid of time-consuming mistakes.

Additionally, Kubernetes cluster helped switch from the extremely outdated on-premise DC that was managed and maintained by on-site staff. Switching allowed to save 2 more full-time positions.

Feedback summary: 

The vendor successfully met stakeholders’ requirements. Coreq was an accommodating group that adapted to timeline changes. They took an accountable, fair approach to the partnership.

The client submitted this review online.

BACKGROUND

Please describe your company and your position there.

I am CTO at a fashion e-commerce project. We offer discounted fashion items to our clients similar to outlets but online.

OPPORTUNITY / CHALLENGE

For what projects/services did your company hire CoreQ?

We started having app downtimes as the traffic went up and we decided to move to cluster. We hired Coreq for that.

What were your goals for this project?

Obviously we wanted to increase app availability and reliability and be able to scale as we grow.

SOLUTION

How did you select this vendor?

They reached out to me when I opened the position and offered to interview their developer. I was happy with the results but hesitant about outsourcing the job. But I didn't find same quality guys for competitive price for onsite and selected Coreq.

Describe the project in detail.

We had a series of discovery meetings to discuss our goals. After that they proposed the solution. We finalized scope, team and budget. After that we had weekly or bi-weekly calls to discuss the progress and prioritize the needs. We had some delays on my side but they were understanding and we sucessfully finished the project.

What was the team composition?

I communicated with Lead Dev on the project.

RESULTS & FEEDBACK

Can you share any outcomes from the project that demonstrate progress or success?

They redesigned the whole architecture and set up Kubernetes cluster after transforming monolithic components into microservices. They set up continuous integration aswell.

How effective was the workflow between your team and theirs?

I liked it. I didn't have to project manage them, they didn't just do tasks but they designed the solution.

What did you find most impressive about this company?

They are a self-directed team, and that saved me lots of time and effort. Also when their junior didn't know how to do something they didn't bill me for senior guy that helped him.

Are there any areas for improvement?

Not at this time.
