Enabled us to collapse hardware- and software-based solutions into one
The scalability is good for us. The 5440 HW is more than capable of handling our current traffic patterns allowing us to grow and not have to do in-place upgrades in the immediate to near term. It's meeting a small portion of our overall network needs, but provides the solution that we sought out. From a hardware standpoint, it makes up a small fraction of our overall deployment, but the usage behind it is very different from what we utilize our production data center hardware for. As I mentioned, it is just providing outbound NAT-ing for us. As we grow our data center space we would expand its usage and footprint. We typically see changes in traffic due to our organic growth and ramp-up of internal services. We plan to implement the following technologies/strategies in the next three years: keeping up with PFS/ECC encryption standards as they evolve. We may or may not move more applications to public cloud. Also, it's possible we could implement cloud repatriation of applications from public cloud to private data centers.

Routing has supported carrier-grade services and has needed more affordable security options
The features of Juniper MX Series Routers that I find most useful are its nice scalability, redundant power supply, and routing engines. Redundancy is maintained in the router itself, including power redundancy and routing engine redundancy. The routers run mostly all the protocols required for the managed service provider, and security-wise, they also have good features, allowing us to provide IPSec VPN services from the routers. These are the basic, mostly used features that we are utilizing. For Deep Packet Inspection, Juniper MX Series Routers have firewall filters and commands related to routing engine protection, and then packet inspection features are configured. In traffic management with Juniper MX Series Routers, I leverage the policer, shapers, and quality of service parameters for traffic management. I also use OSPF traffic engineering features and MPLS-TE; these are a few features that I employ for traffic management.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"It has freed up a lot of our IP space and has been extremely reliable. We have set it up in a high availability scenario, testing it many times. It has been absolutely perfect in terms of failover."
"The most valuable features are its ease of use and deployment, and being able to collapse several solutions into a single solution, all contained within a single bit of hardware and software."
"It is very easy to use. Both the GUI and CLI interface are consistent, which makes the ease of access throughout various constituencies possible. It's also well-documented and logical."
"We have been able to take a software NAT solution and a third-party hardware NAT solution and collapse them into a single solution on the A10 HW, saving us up to $250,000 by not having to purchase additional IPv4 number pools."
"We have absolutely seen ROI, as it saved us hundreds of IP addresses, and that's like gold."
"Juniper Enterprise Routers is very flexible."
"Juniper MX Series Routers are easy to configure and easy to back up."
"The product is easy to use."
"We use it as a central router for both 10G and 100G ports in our internet exchange backbone to connect our partners and protect our root servers and web servers."
"The functionality and stability are great."
"From my experience in the ISP world, I think that Juniper Enterprise Routers are very good products."
"The flexibility of the MPLS configuration is very good."
"The solution is pretty easy to set up after a bit of training."
 

Cons

"They don't track concurrent port usage. We have to do that in another way and it's not a very clean way. That is something that I know they could do, but they don't."
"There are a couple of features that they could look to implement, versus the workarounds that they have in place. Regarding IPv4 and IPv6, there are a couple of opportunities in there that they are working on, as well."
"One area where Juniper MX Series Routers can be improved is the price point, as Juniper MX Series Routers are expensive, both the hardware and the licensing."
"The pricing is a bit too high."
"There is room for improvement in pricing. The product could be cheaper for smaller networks."
"We'd like them to be capable of adding firewall options to the license."
"There are areas for improvement in Juniper EX Series Ethernet Switches. One aspect that could be enhanced is the pricing; many clients acknowledge the quality of Juniper switches but find the pricing challenging, especially when compared to competitors like Huawei. Additionally, from a feature perspective, there's a desire for improved clarity and ease of configuration in Juniper switches. Some users find it difficult to understand and configure certain aspects, necessitating the use of external tools. This complexity, especially for Internet service providers, can be a barrier. Addressing these concerns could further strengthen the position of Juniper switches in the market."
"Juniper must publish more information about Juniper MX Series Routers."
"The areas of Juniper MX Series Routers that have room for improvement include the port count; for instance, the MX204 has only four 40G or 100G ports, which is quite limited."
"Some of our customers find this product high, as they are comparing to Chinese products."
 

Pricing and Cost Advice

"The cost to buy it initially was a single purchase price. This was a cost for the hardware and software, but we got a year of service with it. Annually, we pay them a service fee, but it's not much money."
"The FlexPool consumption-based licensing model has the ability to spin up VMs as needed for NAT, as well as their ADC, which is their load balancing stuff. We are considering that, as that is a pretty attractive feature."
"The solution is more expensive compared to other solutions."
"$300 to $400 is the hardware cost and for licensing cost, it may be around, for support and all, $100 per year."
"We have to pay for the device and licensing. The support service requires additional costs."
"I would rate the pricing model a seven out of ten, where one is cheap, and ten is expensive. It is not cheap."
"There is a license for this solution and the price is very competitive. The cost is less expensive than some competitors, such as Cisco. There are additional costs for support licenses."
"The price of this solution is better than other competitors, such as Cisco. We receive a lot of discounts which make the price less expensive and attractive."
"An additional license can be purchased for support of a next-generation firewall."
"The prices for Juniper MX Series Routers are reasonable."
