AWS Elastic Load Balancing (ELB) vs Semaphore: What are the differences?
Developers describe AWS Elastic Load Balancing (ELB) as "Automatically distribute your incoming application traffic across multiple Amazon EC2 instances". With Elastic Load Balancing, you can add and remove EC2 instances as your needs change without disrupting the overall flow of information. If one EC2 instance fails, Elastic Load Balancing automatically reroutes the traffic to the remaining running EC2 instances. If the failed EC2 instance is restored, Elastic Load Balancing restores the traffic to that instance. Elastic Load Balancing offers clients a single point of contact, and it can also serve as the first line of defense against attacks on your network. You can offload the work of encryption and decryption to Elastic Load Balancing, so your servers can focus on their main task. On the other hand, Semaphore is detailed as "The continuous integration and delivery platform powering the world’s best engineering teams". Semaphore is the fastest continuous integration and delivery (CI/CD) platform on the market, powering the world’s best engineering teams.
AWS Elastic Load Balancing (ELB) belongs to "Load Balancer / Reverse Proxy" category of the tech stack, while Semaphore can be primarily classified under "Continuous Integration".
Some of the features offered by AWS Elastic Load Balancing (ELB) are:
- Distribution of requests to Amazon EC2 instances (servers) in multiple Availability Zones so that the risk of overloading one single instance is minimized. And if an entire Availability Zone goes offline, Elastic Load Balancing routes traffic to instances in other Availability Zones.
- Continuous monitoring of the health of Amazon EC2 instances registered with the load balancer so that requests are sent only to the healthy instances. If an instance becomes unhealthy, Elastic Load Balancing stops sending traffic to that instance and spreads the load across the remaining healthy instances.
- Support for end-to-end traffic encryption on those networks that use secure (HTTPS/SSL) connections.
On the other hand, Semaphore provides the following key features:
- Docker, Kubernetes, iOS support & 100+ preinstalled Tools
- Customizable Continuous Delivery Pipelines
- Customizable Stages, Parallel Execution and Control Flow Switches
"Easy" is the top reason why over 46 developers like AWS Elastic Load Balancing (ELB), while over 19 developers mention "Easy setup" as the leading cause for choosing Semaphore.
According to the StackShare community, AWS Elastic Load Balancing (ELB) has a broader approval, being mentioned in 724 company stacks & 315 developers stacks; compared to Semaphore, which is listed in 40 company stacks and 17 developer stacks.

When it comes to continuous Integration services, the choice is hard. There are several solutions available and it looks like the dev scene is very split. We've read and reviewed several solutions and we ended up making the choice between Codeship and Semaphore . Although Semaphore is used by slightly more developers, we've experienced a faster and easy flow using Codeship. Both do integrate Slack and GitHub very well, so this is not a point to set them apart. Both have a complex pricing system that is not that easy to calculate and predict. However, out in the wild, we found Codeship to have a better price point at heavy use.
I use an Application Load Balancer to balance the load to the EC2 clusters of nightly.zerotoherojs.com and dojo.zerotoherojs.com.
Addditionally, ELB protects my cluster against DDOS attacks: So it is multi-birds with one stone.
We're progressively migrating from classic ELB to newer ALB for ssl offloading and NLB for internal load balancing.
AWS ELB is used to load balance various web and application services across multiple EC2 instances.
The Bitbucket integration with branch whitelists allows you to conserve your 100 builds this month.
- Application type
- SSL free
- forwarding by rules.
- multiple target groups with only one ALB
For balancing the presentation tier, and for SSL offloading (which is great for performance.)
