Amazon Elastic Container Service (Amazon ECS)

My overall experience with Amazon ECS has been exceptionally positive, leading to a high recommendation and satisfaction rating. There are three primary aspects that I particularly appreciate about Amazon ECS, which stand out as its greatest strengths: First, I value the clear cost and costing model. This is a crucial benefit because it makes it easy to understand the pricing model and, consequently, easy to forecast our cost. The financial transparency offered by ECS is a significant advantage, particularly in a pay-for-what-you-use cloud environment. This clarity ensured that we were very clear on what our needs were and what our needs would end up costing. Our ability to continue to hit kind of our cost estimates has proven the accuracy and reliability of this model, directly contributing to our financial viability and the success of our upfront planning. Second, the service is well documented. Beyond excellent documentation, there is also a healthy peer ecosystem that we can lean on if there are questions. This robust support network, combined with comprehensive documentation, significantly eases the learning curve and troubleshooting processes for our team. From a business standpoint, this accessibility provided a certain level of comfort. Our existing staff were already familiar with AWS, and I was highly confident that we could easily hire new team members who would also be proficient with it. ECS struck the right balance, being not an outdated tech and it wasn't a bleeding edge tech that would necessitate finding a highly niche specialist. Internal adoption was remarkably smooth; our development environment was not really disrupted because of the nature of containerization services. Only one person on our team needed to dedicate a week or two to learn how to bridge the gap between local containers and deploying them in ECS, meaning I did not have to train the entire team upfront. Adoption was very easy because it's well documented, allowing one person to get deeply up to speed, and then, over the next month everybody else was able to basically read the documentation and converse about the process, leading to very organic, very internal training oriented adoption. Third, ECS provides very adequate tooling. There are plenty of ways to monitor, including through through API, through alerting or through the AWS console itself. This comprehensive monitoring capability makes it easy to understand if things are operational at any given time. The robust tooling contributes directly to our ability to maintain operational efficiencies and product functionality and performance, which were key drivers in our decision to purchase the service. Beyond these three explicit points, a core strength of the platform that I greatly value is how Amazon or AWS takes on the vast majority of core infrastructure maintenance and monitoring and upgrades. This is one of the the core strengths of the platform because it liberates our team from having to think about a lot of those, a lot of the upgrades and maintenance cost or complexity. This allows us to focus entirely on monitor our own our applications that run inside them rather than managing the underlying infrastructure. This operational efficiency is a major contributing factor to our business process outcomes and internal operational efficiencies. Furthermore, I appreciate that ECS offers a good mix of usability and scalability. As the CTO of a small and growing company, I needed the comfort and reliability of a more simple model. While Kubernetes offers a lot of capabilities and a lot of complexity and customization and in really deep control, it was not the right fit for our current size. ECS aligns with our hiring strategy, allowing us to bring on individuals comfortable in smaller companies, rather than specialists from gigantic scale ups or from larger enterprise companies accustomed to the inherent complexity of Kubernetes. The fact that ECS is a very proven, very well documented, very well understood service from AWS provided a high level of comfort for our strategic move to AWS, especially as our existing staff were already familiar with AWS services. Our ROI has been achieved with ECS because our upfront estimates regarding time, complexity, and cost have aligned with the reality. We have avoided negative outcomes such as production outages, unforeseen costs, or the need to panic, hire an experts to fix some odd issue. Our ability to staff up train and implement on schedule further underscores the value and reliability of ECS. The service also scales admirably with our business growth, and we have not needed to make any upgrades, expansions, or modifications to the core service post-implementation. This stability and hands-off management of the core infrastructure are significant advantages that we highly value.

The serverless aspect, low maintenance and operational overhead, integration with the rest of AWS services

The most significant factors driving our preference for Amazon Elastic Container Service (ECS) are its deep integration with AWS and its inherent ease of use. As an AWS offering, ECS provides seamless integration within the broader AWS ecosystem, which was a primary decision-making factor. This allows direct access to services from AWS and enables the use of the same IAM services for consistent access across our entire ecosystem, including EC2 and other services. This integration also provides built-in security benefits, eliminating the need for additional security measures as it is automatically linked with our existing IAM accounts. ECS is easier to use, significantly reducing the learning curve for our developers. This ease of use extends to maintainability and integration with other services, which is crucial for developer and integration engineer adoption. It notably helps new developers efficiently pick up the CI/CD pipeline. From a scalability perspective, while our current deployments are mid-scale, ECS is exceptionally scalable and designed to support very large deployments, providing robust confidence for future growth. For instance, our meeting management solution performs very well in terms of scalability. Furthermore, Amazon is renowned for its quality of service, delivering 99.9999% uptime. As a premium customer, we benefit from very rapid responses from their support team, significantly minimizing technical overhead related to uptime and maintenance. Finally, while not necessarily more economical, Amazon services offer commendable transparency in cost usage, providing clear visibility into resource consumption and opportunities for optimization.

While our experience with Amazon ECS has been largely positivethere are definite areas where ECS presents limitations. These are aspects that, while understood during our evaluation and acceptable for our specific needs, could be seen as areas for improvement or factors that might lead other organizations to explore alternative solutions. My primary observations regarding the dislikes or areas for improvement in ECS can be categorized into three main points, as discussed during our conversation: Firstly, there are definite limits to what you can do with it, specifically referring to its limited customization. This characteristic was a crucial distinction and an acknowledged trade-off during our initial evaluation process. For instance, when juxtaposing ECS against Kubernetes, I recognized that Kubernetes, in my experience with larger organizations, provided customization and in really deep control. These capabilities were paramount and actively sought in previous roles where extensive technical control and tailored solutions were a necessity. However, for our current small and growing company, my strategic imperative was to achieve the comfort and reliability of a more simple model. ECS perfectly aligned with this requirement, intentionally foregrounding simplicity and ease of use, even if it meant a deliberate sacrifice of the deepest levels of customization. The inherent downside, then, stemming from this design philosophy, is that if you hit that limitation, you might need to fall back to virtual machines for certain highly specific needs that ECS cannot accommodate directly with its predefined templates or configurations. Alternatively, one might need to go to other version of their containerization service, which offers greater flexibility through its native Kubernetes integration. Therefore, while we deliberately chose ECS for its simplicity and the comfort it offered to our smaller team, the very well-known limitations in its amount of customization remain a recognized factor. This implies that organizations requiring very specific, granular control over their container orchestration environment will eventually find ECS restrictive, potentially prompting them to consider more complex, yet more customizable, platforms. Our choice was a strategic trade-off, where the benefits of simplicity, operational reliability, and ease of adoption demonstrably outweighed the need for extensive customization at our current organizational scale. This limitation, therefore, is not a surprise but a recognized characteristic that defines its operational boundaries and potential scope for certain advanced use cases. Secondly, while ECS undeniably offers good horizontal and vertical scaling capability, this scaling operates within kind of predefined increments. This results in what I describe as coarse grained scaling rather than fine grain scaling on the vertical scaling. This characteristic implies that for scenarios demanding extremely precise or highly granular adjustments to resource allocationsuch as CPU, memory, or instance countsECS might not offer the exact level of control desired by all users. While we have, fortunately, found that ECS scales well with our business growth and we haven't needed to make any upgrades, expansions or modifications to the core service post-implementation for our general expansion needs, this particular aspect of scaling granularity could present a point of friction for highly optimized or exceptionally resource-sensitive workloads. In environments where every unit of compute or memory needs to be meticulously balanced for cost efficiency or peak performance, the predefined increments of ECS's scaling mechanism might inadvertently lead to slight over-provisioning or, conversely, subtle under-provisioning. This could manifest as either slightly higher operational costs due to unused resources or marginally suboptimal performance compared to a system offering truly fine-grained, step-by-step control. This is a nuanced yet important distinction for organizations that experience highly variable loads or possess extremely specific resource demands, where the ability to scale in very small, precise steps is critical for achieving optimal efficiency and stringent cost optimization. Thirdly, when compared to more advanced container orchestration platforms, ECS still involves a little bit of virtual machine management. This characteristic stands in contrast to others, where it's completely serverless. One of the core strengths of the platform that I highly value, and which significantly influenced our decision to migrate to AWS, is that Amazon or AWS takes on the vast majority of core infrastructure maintenance and monitoring and upgrades. This strategic benefit allows us to just monitor our own our applications that run inside them, thereby liberating our team from a significant portion of upgrades and maintenance cost or complexity. However, the residual little bit of virtual machine management in ECS signifies that it is not entirely hands-off at the fundamental infrastructure layer in the way a truly serverless solution. While this amount of management is drastically reduced compared to managing our own Kubernetes cluster on AWS infrastructurean option we thoroughly considered and ultimately decided against due to its inherent complexityit is not entirely absent. This subtle but material difference means that there are still some underlying virtual machine considerations that might occasionally surface, potentially requiring a degree of attention that would be entirely absent in a fully serverless environment. For a company that aspires to complete abstraction from all aspects of infrastructure management, this remaining layer of VM oversight in ECS can be perceived as a minor, but present, drawback. It indicates that while ECS heavily abstracts away a multitude of infrastructure concerns, it does not fully eliminate them to the same extent that others do. In summary, while ECS has been an excellent fit for our strategic objectives, enabling us to staff up train and implement on schedule and successfully achieving our ROI by aligning our upfront estimates on time, complexity, and cost with reality, these three points represent its inherent limitations. They are the known trade-offs made in favor of the simplicity, ease of use, and clear, estimable cost model that initially attracted us to the service and continue to provide value. For organizations that unequivocally prioritize deep, granular customization, truly fine-grained scaling, or an unreservedly serverless infrastructure experience, these aspects of ECS would likely be viewed as more significant drawbacks. However, for our specific context and business needs, these are understood boundaries within a highly effective, reliable, and operationally efficient service.

Lack of deep configuration, performance somewhat suffered at times as well

In response to regarding what we dislike most about the product or service, I can state that we have not identified any significant dislikes concerning Amazon Elastic Container Service (ECS) during our extensive use and evaluation. The attributes that contribute to our consistently positive assessment of ECS leave no room for significant dissatisfaction. Other areas, though not rated as exceptional, indicating no significant dissatisfaction.
