Dumping memory on Linux system can be cumbersome especially that the behavior might be different among different GNU/Linux distribution or Linux kernel version. In the early days, the easiest was to dump the memory from the memory device (/dev/mem) but over time the access was more and more restricted in order to avoid malicious process to directly access the kernel memory directly. The kernel option CONFIG_STRICT_DEVMEM was introduced in kernel version 2.6 and upper (2.6.36–2.6.39, 3.0–3.8, 3.8+HEAD). So you'll need to use a Linux kernel module in order to acquire memory.

Choosing a deployment tool - ansible vs puppet vs chef vs salt
- no upfront installation/agents on remote/slave machines - ssh should be enough
- application components should use third-party software, e.g. HDFS, Spark's cluster, deployed separately
- configuration templating
- environment requires/asserts, i.e. we need a JVM in a given version before doing deployment
- deployment process run from Jenkins

Emulating ARM on Debian/Ubuntu
You might want to read this to get an introduction to armel vs armhf.
If the below is too much, you can try Ubuntu-ARMv7-Qemu but note it contains non-free blobs.
First, cross-compile user programs with GCC-ARM toolchain. Then install qemu-arm-static so that you can run ARM executables directly on linux
