Teck Stack Overview
This section delves into our key design choices and the rationale behind each decision, highlighting how these decisions have shaped our infrastructure and services.
Kubernetes for Compute Infrastructure
Our decision to adopt Kubernetes as our compute infrastructure platform early on was significantly influenced by its array of powerful built-in features. Kubernetes stands out for its exceptional ability to dynamically scale applications in response to fluctuating demand, a feature crucial for maintaining efficiency and managing resources. Furthermore, it offers robust solutions for rescheduling and recovery, such as automatically rescheduling and restarting containers in the event of crashes, thereby ensuring high availability. The monitoring capabilities of Kubernetes are also noteworthy, especially with its liveness and readiness probes that provide comprehensive monitoring options.
Additionally, Kubernetes simplifies the complexities of service discovery and integrates seamlessly with load balancing solutions, enhancing the overall performance and reliability of services. The adoption of the Operator Pattern within Kubernetes allows for a high degree of automation in responding to various events within the cluster, thereby boosting operational efficiency. Another significant advantage of Kubernetes is its facilitation of smooth upgrades, both for applications and node/OS, ensuring that our systems remain up-to-date with minimal downtime. Lastly, its cloud agnosticism is a key feature that offers much-needed flexibility and prevents vendor lock-in, allowing us to choose the best tools and services without being restricted to a single provider.

Managed Kubernetes Services
Choosing managed Kubernetes services such as EKS (Elastic Kubernetes Service) in AWS and similar offerings in other cloud environments was a strategic decision for us. The primary appeal of these services lies in their ability to simplify the management of Kubernetes cluster infrastructure. By delegating the complex tasks associated with cluster management to these managed services, we are able to focus more on our core operations and less on the intricacies of Kubernetes. Additionally, this approach significantly accelerates our time to market, a crucial factor especially when operating with a lean team. The ability to quickly deploy and scale our applications without the overhead of extensive infrastructure management is invaluable in maintaining a competitive edge.
Network Isolation with AWS CNI
Our network strategy effectively leverages the AWS Container Network Interface (CNI), chosen for its seamless integration and robust capabilities within the AWS ecosystem. The key aspect of AWS CNI is its ability to directly plug Kubernetes pods into the AWS virtual network. This integration is crucial as it facilitates direct and efficient interactions with various AWS services, enhancing the overall performance and scalability of our applications. As a Container Network Interface solution, AWS CNI excels in managing network interfaces for Linux containers specifically in the AWS environment. This management is essential for ensuring that each container has the necessary network resources to perform optimally.
Moreover, AWS CNI stands out for supporting the high-performance networking features of AWS. These features are integral to maintaining optimal communication standards and robust security within our network. By utilizing these advanced networking capabilities, we ensure that our network infrastructure is not only highly efficient but also adheres to the highest standards of security and performance.
Pricing and Billing
ChistaDATA DBaaS: This innovative platform is designed to streamline the customer experience by eliminating the need for any initial investment in infrastructure. With ChistaDATA Cloud, customers can easily set up and manage their databases, all hosted on a secure and reliable external infrastructure.
Understanding the varied needs of our clients, ChistaDATA Cloud offers a range of subscription plans tailored to meet specific requirements. In addition, the platform is versatile, supporting hosting on popular cloud infrastructures like AWS, GCP, and Azure, giving clients various database hosting options. Key features such as data replication, fail-over, and backup are integrated into each subscription plan, ensuring comprehensive and robust data management.
Our billing model for ChistaDATA DBaaS is transparent and user-friendly, with charges based on actual resource utilization. This includes the combined cost of cloud compute, block storage, object storage, and a service fee for each active server, with billing conducted monthly based on the previous month’s usage.
This clear, flexible, and predictable billing model is especially advantageous for SaaS businesses, as it provides a straightforward understanding of costs. At ChistaDATA, we value this approach, reflecting our commitment to offering customer-centric services that are both transparent and easy to understand.
In the Pipeline Add-ons
We’re excited to share our exciting upcoming features that our dedicated team is actively working on:
1. Bring Your Own Kubernetes: Whether you’re operating within your on-premise infrastructure or utilizing a public/private cloud, we’re introducing ChistaDATA DBaaS Anywhere. This innovation offers a convenient avenue for cloud management of ChistaDATA DBaaS while empowering users to retain control over their data within their own cloud Virtual Private Clouds (VPCs) and private data centers. All the while, you can enjoy the benefits of running managed ClickHouse within your personally curated Kubernetes clusters. The ChistaDATA Cloud Manager UI simplifies the management of ChistaDATA DBaaS Anywhere environments, mirroring the experience of fully hosted ChistaDATA DBaaS environments. You’ll have the ability to oversee multiple environments from a single ChistaDATA DBaaS account and even mix and match different environment types. The best part? ClickHouse management remains consistent and user-friendly, regardless of the environment you’re in.
2. Add ChistaDATA DBaaS to Cloud Marketplace: We’re also excited to announce that you’ll soon find ChistaDATA DBaaS on the Cloud Marketplace. This addition will provide you with even more accessibility to our powerful database-as-a-service solution, making it easier than ever to integrate ChistaDATA DBaaS into your cloud ecosystem.
