Magnetohydrodynamic (MHD) oscillatory processes in different plasma systems, such as the corona of the Sun and the Earth's magnetosphere show interesting similarities and differences, which so far received little attention and remain underexploited. The consolidated understanding of MHD wave processes in the corona and magnetosphere opens up interesting perspectives for effective knowledge transfer and cross-fertilisation of these two research fields. We review several important topics, such as Alfvenic resonances and mode conversion; MHD waveguides, e.g. the magnetotail, coronal loops, coronal streamers; mechanisms for periodicities produced in energy releases during substorms and solar flares, possible drivers of MHD waves; and diagnostics of plasmas with MHD waves. The main attention is paid to the effects of the plasma non-uniformity.
