CA API Management Scalability Issues

Sam Bachman
Owner at Clarity Iq Inc
In my use case, I've not dealt with the type of data that usually responds to the scalability issue. Generally, when people ask that question, they're talking about scalability of hits, scalability of users. Where, all of a sudden now, you have tens of thousands of records happening within a very short period of time - will this scale? I don't have tens of thousands of records happening in split seconds. However, I do know that the product's been tested to that and has demonstrated outstanding scalability results in that regard. There are other aspects of scalability. You might consider how well can I bring on new customers, how well can I scale my development team, how well can I handle additional API integration. Because of the efficiency of the product actually doing that, pulling data from disparate sources, and integrating it into the response format that I want, that my customer demands, that's so easy. It's 10 times, 40 times, 100 times faster than the way we used to do it, and that makes it very scalable. View full review »
Solution Architect at a pharma/biotech company with 1,001-5,000 employees
We're relatively new to this so I don't think we're taxing the capacity of our gateway at all. In the business that we're in, I don't think that we're going to get to huge volumes anyways. Our goal is to leverage it more. So far, that hasn't been an issue at all. The biggest thing for us would be that currently it is deployed in one region. We're a global company, so that technically is a little bit of a constraint for us. We haven't been able to deploy more gateways in other regions mainly due to cost of licensing. View full review »
Director of Architecture at a healthcare company with 1,001-5,000 employees
It's challenging at this point because the healthcare API marketplace is growing. CA API Management has been chosen as the platform for the entire firm so now as the APIs are growing the API management product capability also has to grow. Some of the challenges we are facing is sometimes you have mainframe systems and these mainframe systems are incredibly slow to respond. Now your product has to be capable of keeping your response times open for that duration, so that's one challenge. The ability to scale up, we face that beyond 90,000 or 100,000 transactions, the product has this limitation and it cannot scale. We are seriously facing challenges around response time per transaction and our business demands .1 milliseconds of response time. However, we are seriously reaching up to 3 seconds for some of it. I think internally we have to make this serious call around leveraging CA API Management for certain kind of transactions. Maybe segregate the platform so there are different architecture strategies for it, different approaches for it and we can really achieve it but we need to tune it a lot better. View full review »

Sr. Manager - Technology Governance and Architecture at a tech company with 1,001-5,000 employees
We are able to scale both horizontal and vertically, so we have an internal user base as well as external user base and we are able to provision both for those user needs. We are able to even segment it. One of the features that we like the most is the ability to have a form of servers which provide that scalability and un-scalability at the same time we being able to curve out a part of it exclusively for internal users as well as for external users, but if time demands we can bring that together to scale it. That’s the part which really added a lot more value to the business. View full review »

As mentioned, that's one of the great features, the scalability. We were able to scale up in incidences as needed, and scale down. So again, completely flexible. Top-rate, from the scalability point of view. View full review »

The scalability has been good. Now we have exposed the APIs, we have a four-node cluster of API Gateways in production. It's been scaling out well for us. I haven't had any issue yet. View full review »
James Lepianka
Manager, .Net And Mobile Applications Development at a energy/utilities company with 1,001-5,000 employees
It's definitely a scalable solution, so you can create clusters in production. What we've done is, we got a cluster on our main data center, and then we've got one in our backup data center. Then we can add on to that as we need to, and use the load balancing functionality to scale it indefinitely, as much as we need for our load. View full review »

Head of Group Technology at a logistics company with 1,001-5,000 employees
We did our own test to verify scalability and found it was quite scalable. We had no issues. We had done a load test on the application on our own and it was able to scale to a significant number of transactions per second. Based on our architecture and solution that we have, we are comfortable with the level of volume that it can handle. View full review »

The good thing about McCloud being on AWS is scalability which you get by default. Hence, you don't have to worry about how you want to manage your infrastructure. By default, it will look at your load and there are some alarms set on that and then it will act. When you see the peak, it automatically scales to a new instance and when the load is too low, it will kill that new instance that it has created. AWS will help us with that. View full review »
Jeff Nibler
Vice President of API Management Division at a tech company with 51-200 employees
The CA product has outstanding scalability built-in via their “cluster” concept. The Gateways are organized into clusters and adding a new Gateway into an existing cluster is very simple and does not require an admin to configure the newly added Gateway nor manually deploy policy to it; it is all automatic. Stability of the Gateway is rock-solid so long as you follow CA’s best-practices guidelines when provisioning and configuring servers. We have seen sporadic performance issues when clients’ IT Operations team did not follow the guidelines but these were easily remedied by updating VMware configurations to match CA’s recommendations. DRS configuration is an example of this. One must also pay attention to log and audit data as these can grow fast with the high transaction counts of today’s API utilizations. Implementing a strategy to archive this data is important. We very often forward this data into Splunk to provide our clients with a single source for API analytics. View full review »
Pradeep Bharadwaj
Computer Scientist at a tech company with 1,001-5,000 employees
The scalability is always an issue, as we cannot add gateways on the fly because there are a lot of moving parts; endpoint connectivity is one of them. If we add more nodes then the rate-limiting feature is affected. This kind of gateway always has the scalability issue. But, I think CA is coming up with its Microgateway, which is in Beta. If they stabilize their Microgateway platform, we could do very well in terms of scalability. View full review »

The scalability has been good. We haven't had to scale up a whole lot, even with all the extra transactions we're running through it. We're in the area of about 2 and 1/2 million OAuth tokens issued per hour, and it's performing fine with that. View full review »
Richard Lobovsky
VP Enterprise Solutions - Financial Services at Samsung
The solution is already supporting about five and a half million consumers in South Korea, so it is scalable. Today, there is a server element to that solution. From the client's side, it is SDK-based, but there is a server element. We can support about two million users on each server, then you can nest servers together. We have no concerns about scalability at this point. View full review »

OSS Enterprise Architect
Scalabillity, like most things, is in the hands of your own business to implement. The gateway is flexible and can be scaled to the level you see fit. Be aware though, verbos logging will bring your platform down in seconds, so only use in non-production environments. View full review »

Integration Platform Manager at a comms service provider with 1,001-5,000 employees
We're only receiving 200,000 calls a day at the moment, and we're increasing that to about 1,000,000 calls a day, which is a lot of traffic compared to some customers but I'm sure it's not much compared to others. The performance is fine. View full review »

Programmer Analyst at a healthcare company with 1,001-5,000 employees
We began with just one appliance. Then, as our needs grew, we put in a load balancer. It had multiple VMs talking together, which was fairly easy to do and we never had a problem with that either. From time to time, when we needed to take one server out of the load, it was an easy process; the other servers automatically absorbed the workload. That's a benefit for us. View full review »
Lou Powell
Founding Partner - Principal at Vanick Digital
It's enterprise class software. It gives you the ability to scale and load balance, and based on how the technology is being managed today using a database as an underlying component that allows you to synchronize multiple gateways to the database. And then the ability to cluster the data technology. It can scale as much as you need to scale. View full review »
Director Identity & Access Management at a consultancy with 1,001-5,000 employees
In terms of scalability, we haven't encountered any issues. Scalability has been something that we're starting to explore a little bit more now - automated scalability - responding to increases in capacity in the environment. But we haven't had any issues, and I don't necessarily anticipate any issues. CA provides certain containerized versions of their components that are very easy to deploy and scale. View full review »
Software Engineer at a tech services company with 1,001-5,000 employees
The scalability has been great for us. We have consumers that range from 10 to 20 users upwards to 1000s of users. Thus, it scales really well. It does a lot of load balancing and other nice, little technical tricks that help smooth out requests which come in. View full review »
Sr. Manager - Delivery, Enterprise & Platform Architect at a tech company with 1,001-5,000 employees
Scalability is really good and they could do an average transaction size of probably 50-100KB with around 20,000 transactions per second, which is really impressive. Initially we thought we needed many licenses, but we ended up using only one part of the licenses. View full review »
